Overview
The AD5542AR-REEL7 is a 16-bit, single-channel 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 designed for high precision and reliability. The AD5542 series is known for its low power consumption, fast settling time, and compatibility with various interface standards such as SPI, QSPI, MICROWIRE, and DSP.
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. It also features unbuffered outputs, low noise performance, and low glitch, making it suitable for deployment across multiple end systems.
