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.

Features
  • Conditions 0-2.5V to +/-10V Output
  • 0.1%FSR Uncalibrated Error
  • DAC8560 with 2ppm/°C Internal Reference
  • OPA188 Zero-offset, Zero-Drift Amplifier
This verified design includes:
  • Theory
  • Component Selection
  • TINA-TI Simulation
  • Schemics and PCB Layout
  • Verification and Measured Performance
  • Modification Options
