Overview
The AD7564BN, produced by Analog Devices Inc., is a low-power, quad 12-bit digital-to-analog converter (DAC) integrated into a single monolithic device. This component is designed for versatility and efficiency, operating from a single +3.3 V to +5 V supply. It features four standard current output DACs, each with separate VREF, IOUT1, IOUT2, and RFB terminals. The AD7564BN is ideal for applications requiring multiple DACs in a compact form factor, making it suitable for various industrial and instrumentation uses.
