Overview
The AD7564BNZ, 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 AD7564 features four independent DACs, each with separate VREF, IOUT1, IOUT2, and RFB terminals, making it versatile for various applications. The device supports a serial input interface and is available in 28-pin SOIC, SSOP, and DIP packages.
