GENERAL DESCRIPTION

The AD5744R is a quad, 14-bit, serial input, bipolar voltage output digital-to-analog converter that operates from supply voltages of ±11.4 V up to ±16.5 V. Nominal full-scale output range is ±10 V. The AD5744R provides integrated output amplifiers, reference buffers and proprietary power-up/powerdown control circuitry. The parts also feature a digital I/O port, which is programmed via the serial interface and an analog temperature sensor. The part incorporates digital offset and gain adjust registers per channel.
