Overview
The AD664JPZ, manufactured 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 chip, each with a double-buffered input latch structure and a data readback function. The AD664JPZ is designed to interface easily with a wide variety of microprocessors through its microprocessor-compatible input/output (I/O) port, which supports 4-bit, 8-bit, or 12-bit parallel words. The device operates from a single external reference voltage and can be configured for unipolar or bipolar output ranges with adjustable gain. The AD664JPZ is built using Analog Devices' BiMOS II process, incorporating laser-trimmed thin film resistors and double-level metal interconnects, ensuring high performance and reliability.
