The AD7564 is a serial input device that utilizes FSIN, CLKIN, and SDIN to load data. Two address pins, A0 and A1, allow for device addressing, which simplifies device loading in a multi-DAC environment. Alternatively, A0 and A1 can be ignored and the serial output function can be used to daisy-chain the system.
The asynchronous LDAC input can update all DACs at the same time, while the positioned asynchronous CLR input can clear all DACs.
The device is available in 28-pin SOIC, SSOP, and DIP packages.
