Overview
The AD5543CRMZ-REEL7 is a precision 16-bit digital-to-analog converter (DAC) produced by Analog Devices Inc. This device is part of the AD5543/AD5553 series, designed for low power consumption and compact form factor. It operates from a single 5 V supply and uses a ±10 V multiplying reference to determine the full-scale output current. The AD5543CRMZ-REEL7 features an internal feedback resistor (RFB) that facilitates R-2R and temperature tracking for voltage conversion when combined with an external operational amplifier. The device is packaged in an ultracompact 8-lead MSOP package, measuring 3 mm × 4.7 mm.
