12-bit, Up Compatible, Double-buffered D To A Converters - National Semiconductor

The DAC1208 and the DAC1230 series are 12-bit multiply- ing D to A converters DAC1208 DAC1209 DAC1210 DAC1230 DAC1231 DAC1232 designed to Interface directly with a wide variety of Microprocessors (8080, 8048, 8085, Z-80, etc.). Double buffering input Registers and associated con- trol lines allow these DACs to appear as a two-byte stack in the systems memory or I/O space with no additional in- terfacing Logic required. The DAC1208 series provides all 12 input lines to allow sin- gle buffering for maximum throughput when used with 16-bit processors. These input lines CAN also be externally config- ured to permit an 8-bit data Interface The DAC1230 series CAN be used with an 8-bit data bus directly as it internally formulates the 12-bit DAC data from its 8 input lines. All of these DACs accept left-justified data from the processor. The Analog section is a precision silicon-chromium (Si-Cr) R-2R ladder network and twelve CMOS current switches. An inverted R-2R ladder structure is used with the binary weighted currents switched between the IOUT1 and IOUT2 maintaining a constant current in each ladder leg indepen- dent of the Switch state. Special circuitry provides TTL Logic input voltage level compatibility. The DAC1208 series and DAC1230 series are the 12-bit members of a family of Microprocessor compatible DACs (MICRO-DACsTM). For applications requiring other resolu- tions, the DAC1000 series for 10-bit and DAC0830 series for 8-bit are available alternatives. By National Semiconductor Corporation
