•

Available in 20-Pin SOIC or PLCC Package

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).
