Overview
The AD5312BRM is a dual 10-bit buffered voltage output Digital-to-Analog Converter (DAC) produced by Analog Devices Inc. This component is part of the AD5312 series and is housed in a 10-lead MSOP package. It operates from a single supply voltage ranging from 2.5 V to 5.5 V, making it versatile for various applications. The AD5312BRM features on-chip rail-to-rail output buffer amplifiers, ensuring that the outputs can swing from 0 V to VREF, and it includes a power-on reset circuit that sets the DAC outputs to 0 V upon power-up.
