Overview
The AD5541CR, produced by Analog Devices Inc., is a single, 16-bit, serial input, voltage output digital-to-analog converter (DAC) that operates from a single 2.7 V to 5.5 V supply. This DAC is part of the AD5541 and AD5542 family, known for their low power consumption, high accuracy, and versatile interface compatibility. The AD5541CR is designed to provide a monotonic output range from 0 V to VREF, ensuring ±1 LSB INL accuracy over the full specified temperature range of −40°C to +85°C.
