Напряжение - буферизованноеSPI, DSP11,4 В ~ 16,5 В-40°C ~ 85°C

Overview

The AD5764RCSUZ is a quad, 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 AD5764RCSUZ provides integrated output amplifiers, reference buffers, and proprietary power-up/power-down control circuitry. The part also features a digital I/O port, programmed via the serial interface, and an analog temperature sensor. The part incorporates digital offset and gain adjust registers per channel.

The AD5764RCSUZ uses a serial interface that operates at clock rates of up to 30 MHz and is compatible with DSP and microcontroller interface standards. Double buffering allows the simultaneous updating of all DACs. The input coding is programmable to either twos complement or offset binary formats. The asynchronous clear function clears all data registers to either bipolar zero or zero scale, depending on the coding used. The AD5764RCSUZ is ideal for both closed-loop servo control and open-loop control applications. The AD5764RCSUZ is available in a 32-lead TQFP and offers guaranteed specifications over the −40°C to +85°C industrial temperature range (see Figure 1 for the functional block diagram).
