GENERAL DESCRIPTION

The AD5762R is a dual, 16-bit, serial input, bipolar voltage output DAC that operates from supply voltages of ±11.4 V to ±16.5 V. Nominal full-scale output range is ±10 V. The AD5762R provides integrated output amplifiers, reference buffers, and proprietary power-up/power-down control circuitry. The device also features a digital input/output port, programmed via the serial interface, and an analog temperature sensor. The device incorporates digital offset and gain adjust registers per channel.
