9.2.1 Bipolar ±10-V Analog Output from a Unipolar Voltage Output DAC

This design is used for conditioning a unipolar digital-to-analog converter (DAC) into an accurate bipolar signal source using the OPAx180 family and three resistors. The circuit is designed with reactive load stability in mind, and is compensated to drive nearly any conventional capacitive load associated with long cable lengths.
