Low-Cost, +3V/+5V, 620A, 200MHz, Single-Supply Op Amps with Rail-to-Rail Outputs
General Description
The MAX4452/MAX4352 single, MAX4453/MAX4353 dual, and MAX4454/MAX4354 quad amplifiers combine high-speed performance with ultra-low power consumption. The MAX4452/MAX4453/MAX4454 are unitygain stable and achieve a -3dB bandwidth of 200MHz, while the MAX4352/MAX4353/MAX4354 are compensated for a minimum closed-loop gain of +5V/V and achieve a 80MHz -3dB bandwidth. These devices consume only 620A of supply current per amplifier. These amplifiers operate from a +2.7V to +5.25V single supply and feature Rail-to-Rail(R) outputs. Along with an excellent speed/power ratio of 323MHz/mA, these devices feature a slew rate of 95V/s and fast 20ns rise and fall times. These devices are ideal for lowpower/low-voltage systems that require wide bandwidth such as cell phones and keyless entry systems. The MAX4452/MAX4352 are available in miniature 5-pin SC70 and SOT23 packages, while the MAX4453/ MAX4353 are available in tiny 8-pin SOT23 and SO packages. The MAX4454/MAX4354 are available in space-saving 14-pin TSSOP and SO packages. o Ultra-Low 620A Supply Current o High Speed (MAX4452/MAX4453/MAX4454) 200MHz -3dB Bandwidth 30MHz 0.1dB Gain Flatness 95V/s Slew Rate o High Speed (MAX4352/MAX4353/MAX4354) 80MHz -3dB Bandwidth 4MHz 0.1dB Gain Flatness 240V/s Slew Rate o Single +3V/+5V Operation o Rail-to-Rail Outputs o Input Common-Mode Range Extends Beyond VEE o Ultra-Small SC70-5, SOT23-5, and SOT23-8 Packages

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Detailed Description
The MAX4452/MAX4352 single, MAX4453/MAX4353 dual, and MAX4454/MAX4354 quad, single-supply, railto-rail, voltage-feedback amplifiers achieve high slew rates and wide bandwidths while consuming only 620A per amplifier. Excellent speed/power ratio makes them ideal for portable devices and high-frequency signal applications. Internal feedback around the output stage ensures low open-loop output impedance, reducing gain sensitivity to load variations. This feedback also produces demand-driven current bias to the output transistors. resistors, combined with 2pF of amplifier input capacitance and 1pF of PC board capacitance, causes a pole at 106MHz. Since this pole is within the amplifier bandwidth, it jeopardizes stability. Reducing the 1k resistors to 100 extends the pole frequency to 1.06GHz, but could limit output swing by adding 200 in parallel with the amplifier's load resistor. Note: For high-gain applications where output offset voltage is a consideration, choose RS to be equal to the parallel combination of RF and RG (Figures 3a and 3b). 3b):

Rail-to-Rail Outputs, Ground-Sensing Input
The input common-mode range extends from (VEE 0.1V) to (V CC - 1.5V) with excellent common-mode rejection. Beyond this range, the amplifier output is a nonlinear function of the input, but does not undergo phase reversal or latchup. The output swings to within 180mV of either power-supply rail with a 1k load. The input ground-sensing and the rail-to-rail output substantially increase the dynamic range.

Output Capacitive Loading and Stability
The MAX4452/MAX4453/MAX4454/MAX4352/MAX4353/ MAX4354 are optimized for AC performance. They are not designed to drive highly reactive loads. Such loads decrease phase margin and may produce excessive ringing and oscillation. The use of an isolation resistor eliminates this problem (Figure 1). Figure 2 is a graph of the Optimal Isolation Resistor (RISO) vs. Capacitive Load.

Applications Information
Choosing Resistor Values
Unity-Gain Configuration The MAX4452/MAX4453/MAX4454 are internally compensated for unity gain. When configured for unity gain, a 24 feedback resistor (RF) is recommended. This resistor improves AC response by reducing the Q of the parallel LC circuit formed by the parasitic feedback capacitance and inductance. Inverting and Noninverting Configurations Select the gain-setting feedback (RF) and input (RG) resistor values that best fit the application. Large resistor values increase voltage noise and interact with the amplifier's input and PC board capacitance. This can generate undesirable poles and zeros and decrease bandwidth or cause oscillations. For example, a noninverting gain-of-two configuration (RF = RG) using 1k

Active Filters
The low distortion and high bandwidth of the MAX4452/MAX4453/MAX4454 and MAX4352/ MAX4353/MAX4354 make them ideal for use in active filter circuits. Figure 4 is a 15MHz lowpass multiple feedback active filter using the MAX4452.

Layout and Power-Supply Bypassing
These amplifiers operate from a single +2.7V to +5.25V power supply. Bypass V CC to ground with a 0.1F capacitor as close to the pin as possible. Maxim recommends using microstrip and stripline techniques to obtain full bandwidth. Design the PC board for a frequency greater than 1GHz to prevent amplifier performance degradation due to board parasitics. Avoid large parasitic capacitance at inputs and outputs. Whether or not a constant-impedance board is used, observe the following guidelines: * Do not use wirewrap boards due to their high inductance. * Do not use IC sockets because of the increased parasitic capacitance and inductance.

ADC Input Buffer
Input buffer amplifiers can be a source of significant errors in high-speed ADC applications. The input buffer is usually required to rapidly charge and discharge the ADC's input, which is often capacitive. See Output Capacitive Loading and Stability. In addition, since a high-speed ADC's input impedance often changes very rapidly during the conversion cycle, measurement accuracy must be maintained using an amplifier with very low output impedance at high frequencies. The combination of high speed, fast slew rate, low noise, and a low and stable distortion over load makes the MAX4452/MAX4453/MAX4454/MAX4352/MAX4353/ MAX4354 ideally suited for use as buffer amplifiers in high-speed ADC applications.

* Use surface-mount instead of through-hole components for better high-frequency performance. * Use a PC board with at least two layers; it should be as free from voids as possible. * Keep signal lines as short and as straight as possible. Do not make 90 turns; round all corners.
