The DAC0830/DAC0832 8-Bit µP Compatible, Double-Buffered D to A Converters. The DAC0830 is an advanced CMOS/Si-Cr 8-bit multiplying DAC designed to interface directly with the 8080, 8048, 8085, Z80®, and other popular microprocessors. A deposited silicon-chromium R-2R resistor ladder network divides the reference current and provides the circuit with excellent temperature tracking characteristics (0.05% of Full Scale Range maximum linearity error over temperature). The cir- cuit uses CMOS current switches and control logic to achieve low power consumption and low output leakage current errors. Special circuitry provides TTL logic input volt- age level compatibility. Double buffering allows these DACs to output a voltage corresponding to one digital word while holding the next digital word. This permits the simultaneous updating of any number of DACs. The DAC0830 series are the 8-bit members of a family of microprocessor-compatible DACs (MICRO-DAC™).
The DAC0830 and DAC0832 are advanced CMOS/Si-Cr 8-bit multiplying digital-to-analog converters (DACs) designed to interface directly with popular microprocessors such as the 8080, 8048, 8085, and Z80. These devices feature a deposited silicon-chromium R-2R resistor ladder network that provides excellent temperature tracking characteristics and low power consumption. They utilize CMOS current switches and control logic to achieve low output leakage current errors.
