AD7628KNZ (ANALOG DEVICES)

The AD7628KNZ is a monolithic dual 8-bit Digital-to-analog Converter featuring excellent DAC-to-DAC matching. Separate on-chip latches are provided for DAC to allow easy microprocessor interface. Data is transferred into either of the two DAC data latches via a common 8-bit TTL/CMOS compatible input port. Control input DAC A/DAC B determines which DAC is to be loaded. The AD7628 load cycle is similar to the write cycle of a random access memory and the device is bus compatible with most 8-bit microprocessors. The device operates from a 12 to 15V power supply and is TTL-compatible over this range. It offers excellent four quadrant multiplication characteristics with a separate reference input and feedback resistor for each DAC.
