Overview
The AD5312BRMZ-REEL7 is a dual 10-bit buffered voltage output Digital-to-Analog Converter (DAC) produced by Analog Devices Inc. This component operates from a single 2.5 V to 5.5 V supply and is housed in a 10-lead MSOP package. It is designed for low power consumption, making it suitable for portable battery-operated equipment and various industrial applications. The AD5312 features on-chip output amplifiers that allow the outputs to swing rail-to-rail, and it utilizes a versatile 3-wire serial interface compatible with standard SPI, QSPI, MICROWIRE, and DSP interface standards.
