The AD7564 is a monolithic device with four 12-bit DACs. These DACs provide standard current outputs with separate V
REF、I
OUT1、I
OUT2and R
FBpins that operate from a single +3.3 V to +5 V supply.
The AD7564 is a serial input device that uses FSIN, CLKIN, and SDIN to load data. The device address can be set on two address pins, A0 and A1, which simplifies device loading in multiDAC environments. Alternatively, A0 and A1 can be ignored and the daisy-chain system can be configured with the serial output function.
Take advantage of asynchronyLDACThe inputs can update all DACs at the same time, while asserting is asynchronousCLRThe input clears all DACs.
The device is available in 28-pin SOIC, SSOP, and DIP packages.
