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?).
