Overview
The AD5541A, produced by Analog Devices Inc., is a single, 16-bit, serial input, unbuffered voltage output digital-to-analog converter (DAC). It operates from a single supply voltage ranging from 2.7 V to 5.5 V. 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 +125°C. The device is available in various packages, including 3 mm × 3 mm, 10-lead LFCSP and 10-lead MSOP, and a 3 mm × 3 mm, 8-lead LFCSP for the AD5541A-1 model.
