The DAC8222 is a dual 12-bit, double-buffered, CMOS digitalto-analog converter. It has a 12-bit wide data port that allows a 12-bit word to be loaded directly. This achieves faster throughput time in stand-alone systems or when interfacing to a 16-bit processor. A common 12-bit input TTL/CMOS compatible data port is used to load the 12-bit word into either of the two DACs. This port, whose data loading is similar to that of a RAM's write cycle, interfaces directly with most 12-bit and 16-bit bus systems. (See DAC8248 for a complete 8-bit data bus interface product.) A common bus allows the DAC8222 to be packaged in a narrow 24-lead 0.3" DIP and save PCB space. The DAC is controlled with two signals, WR and LDAC. With logic low at these inputs, the DAC registers become transparent. This allows direct unbuffered data to flow directly to either DAC output selected by DAC A/DAC B. Also, the DAC's
