Product Introduction

Overview

The AD5545CRUZ-REEL7, produced by Analog Devices Inc., is a dual, current-output, serial-input digital-to-analog converter (DAC) available in a compact 16-lead TSSOP package. This device is part of the AD5545/AD5555 series, offering 16-bit and 14-bit resolution options. The AD5545CRUZ-REEL7 specifically features a 16-bit resolution. It operates from a single 4.5 V to 5.5 V supply range and requires an external reference voltage to establish the full-scale output current. The device includes an internal feedback resistor (RFB) that enhances resistance and temperature tracking when used with an external op-amp for I-to-V conversion. The serial data interface is 3-wire microcontroller compatible, using serial data in (SDI), clock (CLK), and chip select (CS) pins, and includes an additional LDAC function for simultaneous update operations.
