Overview
The AD5542LRZ is a 16-bit, serial-input, voltage-output digital-to-analog converter (DAC) produced by Analog Devices Inc. This component operates from a single 2.7 V to 5.5 V supply and is part of the AD5542 family. The DAC output range extends from 0 V to VREF and is guaranteed monotonic, providing 1 LSB INL accuracy at 16 bits without adjustment over the full specified temperature range of −40°C to +85°C. The AD5542LRZ is known for its low power consumption, low offset errors, and fast settling time, making it suitable for various high-performance applications.
