Design files

Overview

This TI Precision Verified Design provides the theory, component selection, simulation, PCB design, and measurement details for a dual-supply, four-quadrant MDAC solution that can accurately generate output voltages from -10V to +10V.  By removing the summing stage, this design also serves as reference for designing a simple two-quadrant MDAC circuit.

Features
  • +/-10V Bipolar output voltage with 0.1% error
  • How to choose an MDAC output amplifier
  • Dual-Supply Solution
  • Four-Quadrant MDAC Configuration
  • Two-Quadrant MDAC Circuit
