GENERAL DESCRIPTION

The AD5744/64 is a quad, 14/16-bit serial input, voltage output digital-to analog converter that operates from supply voltages of ±12 V up to ±15 V. Nominal full-scale output range is ±10 V, provided are integrated output amplifiers, reference buffers, internal reference, and proprietary power-up/power-down control circuitry. It also features a digital I/O port that may be programmed via the serial interface, and an analog temperature sensor. The part incorporates digital offset and gain adjust registers per channel.
