The AD7564 contains four 12-bit DACs in one monolithic device. The DACs are standard current output with separate 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. Alternatively, A0 and A1 can be ignored and the serial out capability used to configure a daisy-chained system. All DACs can be simultaneously updated using the asynchronous LDAC input, and they can be cleared by asserting the asynchronous CLR input. The device is packaged in 28-pin SOIC, SSOP and DIP packages. APPLICATIONS Process control Portable instrumentation General purpose test equipment
