The DAC0830 is an advanced CMOS/si-cr 8-bit mutiplying 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 tempreature tracking characteristics(0.05% of Full Scale Range maximum linearity error over tempreature).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.
