8-bit Microprocessor Compatible, Double-Buffered D/A Converter
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 circuit uses CMOS current switches and control Logic to achieve low power consumption and low output leakage current errors. Special circuitry provides TTL Logic input voltage 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?).
