DAC8218 - DIGITAL-TO-ANALOG CONVERTER

General Description

The DAC8218 is a low-power, octal, 14-bit digital-to-analog converter (DAC).

With a 5V reference, the output can either be a bipolar ±15V voltage when operating from dual ±15.5V (or higher) power supplies, or a unipolar 0V to +30V voltage when operating from a +30.5V (or higher) power supply.
