The AD7564BRZ is a 12-bit monolithic Digital-to-analog Converter (DAC) operates from a single 3.3 to 5V supply. The DAC is standard current output with separate VREF, IOUT1, IOUT2 and RFB terminals. Data is loaded using FSIN, CLKIN and SDIN. Two address pins A0 and A1 set up a device address and this feature may be used to simplify device loading in a multi-DAC environment. Alternatively, A0 and A1 can be ignored and the serial out capability used to configure a daisy-chained system. It can be simultaneously updated using the asynchronous LDAC input and they can be cleared by asserting the asynchronous CLR input.
