Overview
The AD7568BPZ, produced by Analog Devices Inc., is an octal 12-bit digital-to-analog converter (DAC) integrated into a single monolithic device. This IC features eight independent 12-bit DACs, each with standard current output and separate VREF, IOUT1, IOUT2, and RFB terminals. The device is designed for serial input, utilizing FSIN, CLKIN, and SDIN for data loading, and includes an address pin (A0) for multi-DAC environments. It supports simultaneous update of all DACs via the asynchronous LDAC input and reset functionality through the CLR input. The AD7568BPZ is available in space-saving 44-pin PLCC and PQFP packages.
