DAC7716EVM

This user's guide describes the characteristics, operation, and use of the DAC7716EVM. The evaluation
module (EVM) is an evaluation board that allows for quick and easy evaluation of the

DAC7716

. The

DAC7716 is a quad, high-accuracy, 12-bit R-2-R digital-to-analog converter (DAC). The device features
low-power operation, good linearity, and the ability to use different reference voltages for the output
channels. This EVM allows evaluation of all aspects of the DAC7716. Complete circuit descriptions,
schematic diagrams, and bill of material are included in this document.
