The AD7564 contains four 12-bit DACs in one monolithic device. The DACs are standard current output with sepa rate VREF, IOUT1, IOUT2 and RFB terminals. These DACs operate from a single +3.3 V to +5 V supply.
The AD7564 is a serial input device. 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. Alterna tively, A0 and A1 can be ignored and the serial out capability used to configure a daisy-chained system.
All DACs AD7564 can be simultaneously updated using the asynchronous LDAC input, and they can be cleared by asserting the asynchronous CLR input.
The device AD7564 is packaged in 28-pin SOIC, SSOP and DIP packages.
