GENERAL DESCRIPTION

The DAC8248 is a dual 12-bit, double-buffered, CMOS digitalto-analog converter. It has an 8-bit wide input data port that interfaces directly with 8-bit microprocessors. It loads a 12-bit word in two bytes using a single control; it can accept either a least significant byte or most significant byte first. For designs with a 12-bit or 16-bit wide data path, choose the DAC8222 or DAC8221.
