Overview
The AD5541A, specifically the AD5541ABRMZ-REEL7, is a single, 16-bit, serial input, unbuffered voltage output digital-to-analog converter (DAC) produced by Analog Devices Inc. This device operates from a single supply voltage ranging from 2.7 V to 5.5 V, making it versatile for various applications. The DAC output range extends from 0 V to VREF, ensuring monotonicity and ±1 LSB INL accuracy over the full specified temperature range of −40°C to +125°C. The AD5541A is available in several package options, including 10-lead MSOP and 10-lead LFCSP, as well as an 8-lead LFCSP for the AD5541A-1 version.
