Digital to Analogue Converters
- National Semiconductor DAC0832LCN, The DAC0830 is an advanced CMOS/ Si-Cr 8-bit multiplying DAC designed to interface directly with the 8080, 8048, 8085, Z80®, & other popular microprocessors. A deposited silicon-chromium R-2R resistor ladder network divides the reference current & 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 & control logic to achieve low power consumption & 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.
