DAC0830/DAC0831/DAC0832 8-Bit mP

Compatible, Double-Buffered D to A Converters

General Description

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

Features

Double-buffered, single-buffered or flow-through digital

data inputs

DAC designed to interface directly with the 8080, 8048,

8085, Z80 , and other popular microprocessors. A deposit-

Easy interchange and pin-compatible with 12-bit

DAC1230 series

ed 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.

Direct interface to all popular microprocessors

Linearity specified with zero and full scale adjust onlyÐ

NOT BEST STRAIGHT LINE FIT.

Works with 10V reference-full 4-quadrant

multiplication

Can be used in the voltage switching mode

Logic inputs which meet TTL voltage level specs (1.4V

logic threshold)

Double buffering allows these DACs to output a voltage cor-

responding to one digital word while holding the next digital

word. This permits the simultaneous updating of any num-

ber of DACs.

Operates ‘‘STAND ALONE’’ (without mP) if desired

Available in 20-pin small-outline or molded chip carrier

package

The DAC0830 series are the 8-bit members of a family of

microprocessor-compatible DACs (MICRO-DAC^TM). For ap-

plications demanding higher resolution, the DAC1000 series

(10-bits) and the DAC1208 and DAC1230 (12-bits) are avail-

able alternatives.
