Overview
The AD5764RCSUZ is a quad, 16-bit, serial input, bipolar voltage output digital-to-analog converter (DAC) manufactured by Analog Devices Inc. This device operates from supply voltages of ±11.4 V to ±16.5 V and features a nominal full-scale output range of ±10 V. The AD5764RCSUZ is designed using the iCMOS® technology platform, which enables high-performance analog ICs with reduced power consumption and package size, while enhancing both AC and DC performance.
The device includes integrated output amplifiers, reference buffers, and proprietary power-up/power-down control circuitry. It also features digital offset and gain adjust registers per channel, ensuring high accuracy and flexibility. The AD5764RCSUZ is compatible with DSP and microcontroller interface standards and supports clock rates up to 30 MHz.
