9 / 12 page REV. B OP200 –9– Precision Absolute Value Amplifier The circuit in Figure 5 is a precision absolute value amplifier with an input impedance of 10 M Ω. The high gain and low TCVOS of the OP200 ensure accurate operation with microvolt input signals. In this circuit, the input always appears as a common-mode signal to the op amps. The CMR of the OP200 exceeds 120 dB, yielding an error of less than 2 ppm. 1/2 OP200AZ VOUT 1/2 OP200AZ 7 6 5 VIN 3 2 0V < VOUT < 10V 1 R1 1k R3 1k C1 30pF D1 1N4148 C2 0.1pF –15 D1 1N4148 R2 2k C2 0.1pF +15 8 4 Figure 5. Precision Absolute Value Amplifier Precision Current Pump Maximum output current of the precision current pump shown in Figure 6 is ±10 mA. Voltage compliance is ±10 V with ±15 V supplies. Output impedance of the current transmitter exceeds 3 M Ω with linearity better than 16 bits. 1/2 OP200EZ 1/2 OP200EZ 5 6 VIN 3 2 1 R5 100 –15 +15 IOUT 7 R1 10k R2 10k R3 10k R4 1k IOUT = = VIN RS VIN 100 = 10mA/V 8 4 Figure 6. Precision Current Pump Dual 12-Bit Voltage Output DAC The dual output DAC shown in Figure 7 is capable of providing untrimmed 12-bit accurate operation over the entire military temperature range. Offset voltage, bias current, and gain errors of the OP200 contribute less than 1/10 of an LSB error at 12 bits over the military temperature range.
