TIPD125
Bipolar ±10-V output from a unipolar DAC reference design for industrial voltage drivers
TIPD125
Overview
This verified design is for conditioning a low-cost, unipolar, generic DAC into an accurate bipolar signal source using an op amp and 3 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 length.
