DescriptionThe AD7568 contains eight 12-bit DACs in one monolithic device. The DACs are standard current output with separate VREF, IOUT1, IOUT2 and RFB terminals.
The AD7568 is a serial input device. Data is loaded using FSIN, CLKIN and SDIN. One address pin, A0, sets up a device address, and this feature may be used to simplify device loading in a multi-DAC environment.
All DACs AD7568 can be simultaneously updated using the asynchronousLDAC input and they can be cleared by asserting the asynchronousCLR input.
The AD7568 is housed in a space-saving 44-pin plastic quad flatpack and 44-lead PLCC.
