DAC0830/DAC0832 8-Bit 碌P Compatible, Double-Buffered D to A Converters

March 2002

DAC0830/DAC0832

8-Bit 碌P Compatible, Double-Buffered D to A Converters

General Description

The DAC0830 is an advanced CMOS/Si-Cr 8-bit multiplying

DAC designed to interface directly with the 8080, 8048,

8085, Z80

廬

, 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 cir-

cuit uses CMOS current switches and control logic to

achieve low power consumption and low output leakage

current errors. Special circuitry provides TTL logic input volt-

age 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
