The OP490 is a high-performance micropower quad op amp that operates from a single supply of 1.6 V to 36 V or from dual supplies of 0.8 V to 18 V. Input voltage range includes the negative rail allowing the OP490 to accommodate input signals down to ground in single-supply operation. The OP490's output swing also includes ground when operating from a single supply, enabling "zero-in, zero-out" operation. The quad OP490 draws less than 20 mA of quiescent supply current per amplifier, but each amplifier is able to deliver over 5 mA of output current to a load. Input offset voltage is under 0.5 mV with offset drift below 5 mV/C over the military temperature range. Gain exceeds over 700,000 and CMR is better than 100 dB. A PSRR of under 5.6 mV/V minimizes offset voltage changes experienced in battery-powered systems. The quad OP490 combines high performance with the space and cost savings of quad amplifiers. The minimal voltage and current requirements of the OP490 make it ideal for batteryand solar-powered applications, such as portable instruments and remote sensors.

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 the OP490 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.

The OP490 can be operated on a minimum supply voltage of 1.6 V, or with dual supplies of 0.8 V, and draws only 60 mA of supply current. In many battery-powered circuits, the OP490 can be continuously operated for hundreds of hours before requiring battery replacement, reducing equipment downtime, and operating costs. High performance portable equipment and instruments frequently use lithium cells because of their long shelf-life, light weight, and high energy density relative to older primary cells. Most lithium cells have a nominal output voltage of 3 V and are noted for a flat discharge characteristic. The low supply current

Figure 4 shows the typical discharge characteristic of a 1 Ah lithium cell powering an OP490 with each amplifier, in turn, driving full output swing into a 100 kW load.

CHANNEL SEPARATION = 20 LOG
Single-Supply Output Voltage Range
In single-supply operation the OP490's input and output ranges include ground. This allows true "zero-in, zero-out" operation. The output stage provides an active pull-down to around 0.8 V above ground. Below this level, a load resistance of up to 1 MW to ground is required to pull the output down to zero. In the region from ground to 0.8 V, the OP490 has voltage gain equal to the data sheet specification. Output current source capability is maintained over the entire voltage range including ground.
Input Voltage Protection
1/4 OP490D
Figure 3. Channel Separation Test Circuit
The OP490 uses a PNP input stage with protection resistors in series with the inverting and noninverting inputs. The high breakdown of the PNP transistors coupled with the protection resistors provides a large amount of input protection, allowing the inputs to be taken 20 V beyond either supply without damaging the amplifier.

Micropower Voltage-Controlled Oscillator
An OP490 in combination with an inexpensive quad CMOS switch comprise the precision VCO of Figure 5. This circuit provides triangle and square wave outputs and draws only 75 mA from a 5 V supply. A acts as an integrator; S1 switches the charging current symmetrically to yield positive and negative ramps. The integrator is bounded by B which acts as a Schmitt trigger with a precise hysteresis of 1.67 V, set by resistors R5, R6, and R7, and associated CMOS switches. The resulting
C1 75nF
output of A is a triangle wave with upper and lower levels of 3.33 V and 1.67 V. The output of B is a square wave with almost rail-to-rail swing. With the components shown, frequency of operation is given by the equation: fOUT = VCONTROL ( Volts) 10 Hz / V but this is easily changed by varying C1. The circuit operates well up to a few hundred hertz.

Micropower Single-Supply Quad Voltage-Output 8-Bit DAC
The circuit of Figure 6 uses the DAC8408 CMOS quad 8-bit DAC, and the OP490 to form a single-supply quad voltage-output DAC with a supply drain of only 140 mA. The DAC8408 is used in voltage switching mode and each DAC has an output resistance
(10 kW) independent of the digital input code. The output amplifiers act as buffers to avoid loading the DACs. The 100 kW resistors ensure that the OP490 outputs will swing below 0.8 V when required.

Figure 7. High Output Amplifier
High Output Amplifier
The amplifier shown in Figure 7 is capable of driving 25 V p-p into a 1 kW load. Design of the amplifier is based on a bridge configuration. A amplifies the input signal and drives the load with the help of B. Amplifier C is a unity-gain inverter which drives the load with help from D. Gain of the high output amplifier with the component values shown is 10, but can easily be changed by varying R1 or R2.
Single-Supply Micropower Quad Programmable Gain Amplifier
where n equals the decimal equivalent of the 8-bit digital code present at the DAC. If the digital code present at the DAC consists of all zeros, the feedback loop will be open causing the op amp output to saturate. The 10 MW resistors placed in parallel with the DAC feedback loop eliminates this problem with a very small reduction in gain accuracy. The 2.5 V reference biases the amplifiers to the center of the linear region providing maximum output swing.
The combination of quad OP490 and the DAC8408 quad 8-bit CMOS DAC, creates a quad programmable-gain amplifier with a quiescent supply drain of only 140 mA. The digital code present at the DAC, which is easily set by a microprocessor, determines the ratio between the fixed DAC feedback resistor and the resistance of the DAC ladder presents to the op amp feedback loop. Gain of each amplifier is: VOUT 256 =VIN n
