Overview
The AD5310BRM-REEL, produced by Analog Devices Inc., is a single, 10-bit, buffered voltage output Digital-to-Analog Converter (DAC) designed for low power and high precision applications. It operates from a single supply voltage ranging from 2.7 V to 5.5 V and is available in an 8-lead MSOP package. This DAC is part of a family of pin-compatible DACs, including the 8-bit AD5300 and the 12-bit AD5320. The AD5310 is particularly suited for portable, battery-operated equipment due to its low power consumption and versatile serial interface.
