GENERAL DESCRIPTION The DAC-8221 combinestwoidentical12-bit,multiplying,digital- to-analog converters into a single CMOS chip. This device is electrically similar to DAC-8212 with improved microprocessor interface timing and is packaged in a narrow 0.300" DI P. Mono- lithic construction offers excellent DAG-to-DAC matching and tracking over the full operating temperature range. The DAG- 8221 consists of two thin-fiim R-2R resistor-ladder networks, two 12-bit data latches, one 12-bit input buffer, and control logic. The DAC-8221 operates on a single supply from +5V to +15V. Maximum power dissipation with 0V and +5V logic levels Information furnished by Analog Devices is believed to be accurate and reliable. However, no responsibility is assumed by Analog Devices for its use, nor for any infringements of patents or other rights of third parties which may result from its use. No license is granted by implication or otherwise under any patent or patent rights of Analog Devices. REV. B Dual 12-Bit Buffered Multiplying CMOS MI Converter DA08221 and a +5V supply is less than 0.5mW. The DAC-8221 is manu- factured using PMI's highly-stable, thin-tilm resistors on an advanced oxide-isolated, silicon-gate, CMOS process, PMI's improved latch-up resistant design eliminates the need for external protective Schottky diodes. Acc)mmon12-bit(TTL/CMOS compatible) input port is used to load a12-bit-wide 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 or wider bus systems. With Wt and tTg lines at logic LOW, the input data registers are trans- parent. This allows direct unbuffered data to flow directly to the DAC output selected by DAC A/DAC B control input. For
