Overview
The AD5543BRMZ-REEL7 is a precision 16-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc. This component is part of the AD5543/AD5553 series, which includes both 16-bit and 14-bit versions. It is designed for low power consumption and features a small form factor, making it suitable for a variety of applications. The DAC operates from a single 5 V supply and uses an external ±10 V multiplying reference to determine the full-scale output current. An internal feedback resistor (RFB) facilitates voltage conversion when used with an external operational amplifier.
