GENERAL DESCRIPTION
The AD8061, AD8062, and AD8063 are rail-to-rail output voltage feedback amplifiers offering ease of use and low cost. They have bandwidth and slew rate typically found in current feedback amplifiers. All have a wide input common-mode voltage range and output voltage swing, making them easy to use on single supplies as low as 2.7 V. Despite being low cost, the AD8061, AD8062, and AD8063 provide excellent overall performance. For video applications their differential gain and phase errors are 0.01% and 0.04 into a 150 load, along with 0.1 dB flatness out to 30 MHz. Additionally, they offer wide bandwidth to 300 MHz along with 650 V/s slew rate. The AD8061, AD8062, and AD8063 offer a typical low power of 6.8 mA/amplifier, while being capable of delivering up to 50 mA of load current. The AD8063 has a power-down disable feature that reduces the supply current to 400 A. These features make the AD8063 ideal for portable and battery-powered applications where size and power are critical.

Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
MAXIMUM POWER DISSIPATION
VS Observe Power Derating Curves -65C to +125C -40C to +85C 300C
Specification is for device in free air. 8-Lead SOIC: JA = 160C/W; JC = 56C/W. 5-Lead SOT-23: JA = 240C/W; JC = 92C/W. 6-Lead SOT-23: JA = 230C/W; JC = 92C/W. 8-Lead MSOP: JA = 200C/W; JC = 44C/W.
The maximum power that can be safely dissipated by the AD806x is limited by the associated rise in junction temperature. The maximum safe junction temperature for plastic encapsulated devices is determined by the glass transition temperature of the plastic, approximately 150C. Temporarily exceeding this limit may cause a shift in parametric performance due to a change in the stresses exerted on the die by the package. Exceeding a junction temperature of 175C for an extended period can result in device failure. While the AD806x is internally short-circuit protected, this may not be sufficient to guarantee that the maximum junction temperature (150C) is not exceeded under all conditions. To ensure proper operation, it is necessary to observe the maximum power derating curves.

ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.

AD8061/AD8062/AD8063 CIRCUIT DESCRIPTION
The AD8061/AD8062/AD8063 family is comprised of high speed voltage feedback op amps. The high slew rate input stage is a true, single-supply topology, capable of sensing signals at or below the minus supply rail. The rail-to-rail output stage can pull within 30 mV of either supply rail when driving light loads and within 0.3 V when driving 150 . High speed performance is maintained at supply voltages as low as 2.7 V.

HEADROOM CONSIDERATIONS
These amplifiers are designed for use in low voltage systems. To obtain optimum performance, it is useful to understand the behavior of the amplifier as input and output signals approach the amplifier's headroom limits. The AD806x's input common-mode voltage range extends from the negative supply voltage (actually 200 mV below this), or ground for single-supply operation, to within 1.8 V of the positive supply voltage. Thus, at a gain of 2, the AD806x can provide full rail-to-rail output swing for supply voltage as low as 3.6 V, assuming the input signal swing from -VS (or ground) to +VS/2. At a gain of 3, the AD806x can provide a rail-to-rail output range down to 2.7 V total supply voltage. Exceeding the headroom limit is not a concern for any inverting gain on any supply voltage, as long as the reference voltage at the amplifier's positive input lies within the amplifier's input common-mode range. The input stage is the headroom limit for signals when the amplifier is used in a gain of 1 for signals approaching the positive rail. Figure 45 shows a typical offset voltage vs. input common-mode voltage for the AD806x amplifier on a 5 V supply. Accurate dc performance is maintained from approximately 200 mV below the minus supply to within 1.8 V of the positive supply. For high-speed signals, however, there are other considerations. Figure 46 shows -3 dB bandwidth vs. dc input voltage for a unity-gain follower. As the common-mode voltage approaches the positive supply, the amplifier holds together well, but the bandwidth begins to drop at 1.9 V within +VS. This manifests itself in increased distortion or settling time. Figure 16 plots the distortion of a 1 V p-p signal with the AD806x amplifier used as a follower on a 5 V supply vs. signal common-mode voltage. Distortion performance is maintained until the input signal center voltage gets beyond 2.5 V, as the peak of the input sine wave begins to run into the upper common-mode voltage limit.

FREQUENCY (MHz)
Figure 46. Unity-Gain Follower Bandwidth vs. Input Common Mode, VS = 5 V
Higher frequency signals require more headroom than lower frequencies to maintain distortion performance. Figure 47 illustrates how the rising edge settling time for the amplifier configured as a unity-gain follower stretches out as the top of a 1 V step input approaches and exceeds the specified input common-mode voltage limit. For signals approaching the minus supply and inverting gain and high positive gain configurations, the headroom limit is the output stage. The AD806x amplifiers use a common emitter style output stage. This output stage maximizes the available output range, limited by the saturation voltage of the output transistors. The saturation voltage increases with the drive current the output transistor is required to supply, due to the output transistors' collector resistance. The saturation voltage is estimated using the equation VSAT = 25 mV + IO x 8 , where IO is the output current, and 8 is a typical value for the output transistors' collector resistance.

As the saturation point of the output stage is approached, the output signal shows increasing amounts of compression and clipping. As in the input headroom case, the higher frequency signals require a bit more headroom than lower frequency signals. Figure 16, Figure 17, and Figure 18 illustrate this point, plotting typical distortion vs. output amplitude and bias for gains of 2 and 5.
Output
Output overload recovery is typically within 40 ns after the amplifier's input is brought to a nonoverloading value. Figure 49 shows output recovery transients for the amplifier recovering from a saturated output from the top and bottom supplies to a point at midsupply.

Input
The specified input common-mode voltage of the AD806x is -200 mV below the negative supply to within 1.8 V of the positive supply. Exceeding the top limit results in lower bandwidth and increased settling time as seen in Figure 46 and Figure 47. Pushing the input voltage of a unity-gain follower beyond 1.6 V within the positive supply leads to the behavior shown in Figure 48--an increasing amount of output error and much increased settling time. Recovery time from input voltages 1.6 V or closer to the positive supply is approximately 35 ns, which is limited by the settling artifacts caused by transistors in the input stage coming out of saturation. The AD806x family does not exhibit phase reversal, even for input voltages beyond the voltage supply rails. Going more than 0.6 V beyond the power supplies will turn on protection diodes at the input stage, which will greatly increase the device's current draw.

CAPACITIVE LOAD DRIVE
The AD806x family is optimized for bandwidth and speed, not for driving capacitive loads. Output capacitance creates a pole in the amplifier's feedback path, leading to excessive peaking and potential oscillation. If dealing with load capacitance is a requirement of the application, the two strategies to consider are as follows: 1. Use a small resistor in series with the amplifier's output and the load capacitance. Reduce the bandwidth of the amplifier's feedback loop by increasing the overall noise gain.

Voltage feedback amplifiers like those in the AD806x family are able to drive more capacitive load without excessive peaking when used in higher gain configurations, because the increased noise gain reduces the bandwidth of the overall feedback loop. Figure 51 plots the capacitance that produces 30% overshoot vs. noise gain for a typical amplifier.

Figure 34 shows the AD8063 supply current vs. DISABLE voltage. Figure 35 plots the output seen when the AD8063 input is driven with a 10 MHz sine wave, and the DISABLE is toggled from 0 V to 5 V, illustrating the part's turn-on and turn-off time. Figure 33 shows the input/output isolation response with the AD8063 shut off.
BOARD LAYOUT CONSIDERATIONS
Maintaining the high speed performance of the AD806x family requires the use of high speed board layout techniques and low parasitic components. The PCB should have a ground plane covering unused portions of the component side of the board to provide a low impedance path. Remove the ground plane near the package to reduce parasitic capacitance. Proper bypassing is critical. Use a ceramic 0.1 F chip capacitor to bypass both supplies. Locate the chip capacitor within 3 mm of each power pin. Additionally, connect in parallel a 4.7 F to 10 F tantalum electrolytic capacitor to provide charge for fast, large signal changes at the output. Minimizing parasitic capacitance at the amplifier's inverting input pin is very important. Locate the feedback resistor close to the inverting input pin. The value of the feedback resistor may come into play--for instance, 1 k interacting with 1 pF of parasitic capacitance creates a pole at 159 MHz. Use stripline design techniques for signal traces longer than 25 mm. Design them with either 50 or 75 characteristic impedance and proper termination at each end.

DISABLE OPERATION
The internal circuit for the AD8063 disable function is shown in Figure 52. When the DISABLE node is pulled below 2 V from the positive supply, the supply current decreases from typically 6.5 mA to under 400 A, and the AD8063 output will enter a high impedance state. If the DISABLE node is not connected and allowed to float, the AD8063 stays biased at full power.

AD8061/AD8062/AD8063 APPLICATIONS
SINGLE-SUPPLY SYNC STRIPPER
When a video signal contains synchronization pulses, it is sometimes desirable to remove them prior to performing certain operations. In the case of A-to-D conversion, the sync pulses consume some of the dynamic range, so removing them increases the converter's available dynamic range for the video information. Figure 53 shows a basic circuit for creating a sync stripper using the AD8061 powered by a single supply. When the negative supply is at ground potential, the lowest potential to which the output can go is ground. This feature is exploited to create a waveform whose lowest amplitude is the black level of the video and does not include the sync level.
3V
The circuit can be modified to provide the sync stripping function for such a waveform. Instead of connecting RG to ground, connect it to a dc voltage that is two times the black level of the input signal. The gain from the +input to the output is two, which means the black level will be amplified by two to the output. However, the gain through RG is -unity to the output. It takes a dc level of twice the input black level to shift the black level to ground at the output. When this occurs, the sync will be stripped, and the active video will be passed as in the ground-referenced case.

In this case, the input video signal has its black level at ground, so it comes out at ground at the input. Since the sync level is below the black level, it will not show up at the output. However, all of the active video portion of the waveform will be amplified by a gain of two and then be normalized to unity gain by the backterminated transmission line. Figure 54 is an oscilloscope plot of the input and output waveforms.

Most RGB graphics signals are created by video DAC outputs that drive a current through a resistor to ground. At the video black level, the current goes to zero, and the voltage of the video is also zero. Before the availability of high speed rail-to rail op amps, it was essential that an amplifier have a negative supply to amplify such a signal. Such an amplifier is necessary if one wants to drive a second monitor from the same DAC outputs. However, high speed, rail-to-rail output amplifiers like the AD8061 and AD8062 accept ground level input signals and output ground level signals. They are used as RGB signal amplifiers. A combination of the AD8061 (single) and the AD8062 (dual) amplifies the three video channels of an RGB system. Figure 55 shows a circuit that performs this function.
Some video signals with sync are derived from single-supply devices, such as video DACs. These signals can contain sync, but the whole waveform is positive, and the black level is not at ground but at some positive voltage.

MULTIPLEXER
The AD8063 has a disable pin used to power down the amplifier to save power or to create a mux circuit. If two (or more) AD8063 outputs are connected together, and only one is enabled, then only the signal of the enabled amplifier will appear at the output. This configuration is used to select from various input signal sources. Additionally, the same input signal is applied to different gain stages, or differently tuned filters, to make a gainstep amplifier or a selectable frequency amplifier. Figure 56 shows a schematic of two AD8063s used to create a mux that selects between two inputs. One of these is a 1 V p-p, 3 MHz sine wave; the other is a 2 V p-p, 1 MHz sine wave.
