Overview
The AD5542ABRUZ is a 16-bit, serial input, unbuffered 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 nanoDAC™ family. It is known for its high precision and speed, making it suitable for a variety of applications requiring accurate and fast analog output.
The AD5542ABRUZ features a DAC output range that 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. It also includes a bipolar mode of operation, generating a ±VREF output swing, and incorporates Kelvin sense connections to reduce layout sensitivity.
