GENERAL DESCRIPTION

The AD5765 is a quad, 16-bit, serial input, bipolar voltage output, digital-to-analog converter (DAC) that operates from supply voltages of ±4.75 V to ±5.25 V. The nominal full-scale output range is ±4.096 V. The AD5765 provides integrated output amplifiers, reference buffers, and proprietary powerup/power-down control circuitry. The part also features a digital I/O port, which is programmed via the serial interface. The part incorporates digital offset nd gain adjustment registers per channel.
