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 DAC0830 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™).
