Overview
The AD7564BR-REEL, produced by Analog Devices Inc., is a quad 12-bit digital-to-analog converter (DAC) integrated into a single monolithic device. This component is designed for low power consumption and operates from a single supply voltage ranging from +3.3 V to +5 V. The AD7564BR-REEL features four standard current output DACs, each with separate VREF, IOUT1, IOUT2, and RFB terminals. This device is particularly useful in applications requiring multiple DACs with independent reference inputs and low power operation.
