The input voltage range includes the negative rail allowing the OP490 to accommodate input signals down to ground in single-supply operation. The output swing of the OP490 also includes ground when operating from a single supply, enabling zero-in, zero-out operation. The quad OP490 draws less than 20 μA 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. Gain exceeds over 400,000 and CMR is better than 90 dB. A PSRR of under 5.6 μV/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 battery and solar-powered applications, such as portable instruments and remote sensors. Rev.

Most lithium cells have a nominal output voltage of 3 V and are noted for a flat discharge characteristic. The low supply current requirement of the OP490, combined with the flat discharge characteristic of the lithium cell, indicates that the OP490 can be operated over the entire useful life of the cell. Figure 21 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 kΩ load. 7 00308-019 GND +18V Figure 19.

Channel Separation Test Circuit 00308-020 VIN 4 00308-021 14 The OP490 can be operated on a minimum supply voltage of 1.6 V or with dual supplies of ±0.8 V drawing only 60 μA of supply current. In many battery-powered circuits, the OP490 can be continuously operated for hundreds of hours before requiring battery replacement, thereby reducing equipment downtime and operating costs. In single-supply operation the input and output ranges of the OP490 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 MΩ 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. Rev. E | Page 9 of 16 OP490 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 the associated CMOS switches. The resulting 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 INPUT VOLTAGE PROTECTION 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 fOUT = VCONTROL (Volts) × 10 Hz/V but this is easily changed by varying C1. The circuit operates well up to a few hundred hertz. An OP490 in combination with an inexpensive quad CMOS switch comprise the precision VCO of Figure 22. This circuit provides triangle and square wave outputs and draws only 75 μA from a 5 V supply.

The DAC8408 is used in voltage switching mode and each DAC has an output resistance (≈10 kΩ) independent of the digital input code. The output amplifiers act as buffers to avoid loading the DACs. The 100 kΩ resistors ensure that the OP490 outputs swing below 0.8 V when required. +5V 4 4 REFERENCE VOLTAGE 1.5V 2 – 3 + A 1/4 IOUT1A OP490 DAC A VREF A 1/4 2 1 DAC8408 11 5 IOUT2A/2B 6 1/4 6 IOUT1B 25 IOUT1C VREF B 1/4 8 5 7 R2 100kΩ 13 – 1/4 VREF C 1/4 OP490 27 12 14 R3 100kΩ IOUT2C/2D 9 – 1/4 DAC D 23 IOUT1D VREF D 1/4 VOUTC + C DAC8408 24 VOUTB + B DAC8408 DAC C R1 100kΩ – OP490 DAC B VOUTA OP490 21 10 8 VOUTD + D DAC8408 R4 100kΩ OP490 DAC DATA BUS PIN 9 (LSB) TO PIN 16 (MSB) DIGITAL CONTROL SIGNALS 18 19 20 A/B R/W DAC8408 DS1 DS2 DGND 28 00308-023 17 Figure 23.

High Output Amplifier HIGH OUTPUT AMPLIFIER The amplifier shown in Figure 24 is capable of driving 25 V p-p into a 1 kΩ 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 The combination of a quad OP490 and the DAC8408 quad 8-bit CMOS DAC creates a quad programmable-gain amplifier with a quiescent supply drain of only 140 μA. 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 seen by the op amp feedback loop. The gain of each amplifier is: VOUT V IN =− 256 n 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 opens causing the op amp output to saturate. The 10 MΩ resistors placed in parallel with the DAC feedback loop eliminate 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. Rev.
