The AD7568 is a serial input device that utilizes FSIN, CLKIN, and SDIN to load data. One address pin A0 sets the device address, which simplifies device loading in a multi-DAC environment.
The asynchronous LDAC input can update all DACs at the same time, while the positioned asynchronous CLR input can clear all DACs.
The AD7568 is available in two space-saving packages: a 44-pin plastic quad flat package and a 44-pin PLCC package.
