DAC1210 - National Semiconductor

DAC1210 12-Bit/ uP Compatible/ Double-Buffered D to A Converters

The DAC1208 and the DAC1230 series are 12-bit multiplying D to A converters designed to interface directly with a wide variety of microprocessors (8080 8048 8085 Z-80 etc ) Double buffering input registers and associated control lines allow these DACs to appear as a two-byte ‘‘stack’’ in the system’s memory or I O space with no additional interfacing logic r.
