Overview
The AD5311BRM-REEL is a 10-bit digital-to-analog converter (DAC) produced by Analog Devices Inc. This component operates from a single 2.5 V to 5.5 V power supply and is designed for low power consumption, making it ideal for portable battery-operated equipment. The AD5311 features a buffered voltage output and uses a 2-wire (I2C compatible) serial interface for data communication. The device includes an on-chip rail-to-rail output buffer amplifier and supports multiple power-down modes to minimize current consumption.
