Overview
The AD7564BR, manufactured by Analog Devices Inc., is a low-power, quad 12-bit CMOS digital-to-analog converter (DAC). This device integrates four 12-bit DACs in a single monolithic package, making it highly versatile for various applications. The DACs are standard current output types with separate VREF, IOUT1, IOUT2, and RFB terminals. The AD7564BR operates from a single +3.3 V to +5 V supply, ensuring compatibility with a wide range of systems.
