Overview
The AD664JP, produced by Analog Devices Inc., is a monolithic 12-bit quad digital-to-analog converter (DAC) integrated circuit. This device features four complete 12-bit, voltage-output DACs on a single IC chip, each equipped with a double-buffered input latch structure and a data readback function. The AD664JP is designed for simplicity in interfacing with various microprocessors through a single microprocessor-compatible input/output (I/O) port, which supports 4-bit, 8-bit, or 12-bit parallel words.
