Overview
The AD5555CRU-REEL7 is a dual, current-output, serial-input digital-to-analog converter (DAC) produced by Analog Devices Inc. This component is part of the AD5545/AD5555 family, designed for high precision and low power consumption. It operates from a single supply voltage ranging from 4.5 V to 5.5 V and is available in a compact 16-lead TSSOP package. The AD5555CRU-REEL7 is particularly suited for applications requiring 14-bit resolution and high-speed data transfer through a 3-wire serial interface.
