The DAC0830 is an advanced CMOS/Si-Cr 8-bit multiplyingDAC designed to interface directly with the 8080, 8048,8085, Z80®, and other popular microprocessors. A depositedsilicon-chromium R-2R resistor ladder network divides thereference current and provides the circuit with excellenttemperature tracking characteristics (0.05% of Full ScaleRange maximum linearity error over temperature). The circuituses CMOS current switches and control logic toachieve low power consumption and low output leakagecurrent errors. Special circuitry provides TTL logic input voltagelevel compatibility.Double buffering allows these DACs to output a voltagecorresponding to one digital word while holding the nextdigital word. This permits the simultaneous updating of anynumber of DACs.The DAC0830 series are the 8-bit members of a family ofmicroprocessor-compatible DACs (MICRO-DAC™).
