DAC8718 - Octal Low power 16-bit +/-15V Output Serial Input DAC
The DAC8718 is a low-power, octal, 16-bit digital-to-analog converter (DAC). With a 5 V reference, the output can either be a bipolar ±15 V voltage when operating from dual ±15.5 V (or higher) power supplies, or a unipolar 0 V to +30 V voltage when operating from a +30.5 V (or higher) power supply. With a 5.5 V reference, the output can either be a bipolar ±16.5 V voltage when operating from dual ±17 V (or higher) power supplies, or a unipolar 0 V to +33 V voltage when operating from a +33.5 V (or higher) power supply. This DAC provides low-power operation, good linearity, and low glitch over the specified temperature range of –40°C to +105°C. This device is trimmed in manufacturing and has very low zero-code and gain error.
