Precision Absolute Value Amplifier
The circuit in Figure 5 is a precision absolute value amplifier
with an input impedance of 10 MΩ. The high gain and low
TCV
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.

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 MΩ with linearity better than 16 bits.
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.
