Overview
The AD5744RCSUZ-REEL7, produced by Analog Devices Inc., is a quad, 14-bit, serial input, bipolar voltage output Digital-to-Analog Converter (DAC). This high-performance converter operates from supply voltages of ±11.4 V to ±16.5 V and features a nominal full-scale output range of ±10 V. The AD5744R incorporates integrated output amplifiers, reference buffers, and proprietary power-up/power-down control circuitry, making it suitable for various high-accuracy applications. It is based on the iCMOS® technology platform, which enables the development of analog ICs with high performance at higher voltage levels while reducing power consumption and package size.
