Overview
The AD5764BSUZ from Analog Devices Inc. is a high-performance, quad-channel, 16-bit digital-to-analog converter (DAC) designed for applications requiring precise and fast analog output. 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. It is integrated with output amplifiers, reference buffers, and proprietary power-up/power-down control circuitry, making it ideal for both closed-loop servo control and open-loop control applications.
The AD5764BSUZ is known for its high accuracy, low noise, and fast settling time of 10 μs. It supports a serial interface compatible with DSP and microcontroller standards, operating at clock rates up to 30 MHz. The device is available in a 32-lead TQFP package and guarantees specifications over the −40°C to +85°C industrial temperature range.
