Product Overview

The AD664BD-BIP is a four complete 12-bit voltage-output Digital-to-analog Converter (DAC) on one monolithic IC chip. The DAC has a double-buffered input latch structure and a data read-back function. DAC read and write operations occur through a single microprocessor-compatible I/O port. The I/O port accommodates 12-bit parallel words allowing simple interfacing with a wide variety of microprocessors. A reset to zero control pin is provided to allow user to simultaneously reset DAC outputs to zero, regardless of the contents of the input latch. The DAC may be placed in a transparent mode allowing immediate response by the outputs to the input data. Each DAC cell is an inverting R-2R type. The output current from each DAC is switched to the on-board application resistors and output amplifier. The output range of each DAC cell is programmed through the digital I/O port and may be set to unipolar or bipolar range with a gain of one or two times the reference voltage.
