Quad 8-Bit Voltage Out CMOS DAC

Complete with Internal 10 V Reference

DAC8426

FEATURES

offering a 25 ppm/°C temperature coefficient and 5 mA of exter-

No Adjustm ents Required, Total Error ؎1 LSB Max

Four Voltage-Output DACs on a Single Chip

Internal 10 V Bandgap Reference

Operates from Single ؉15 V Supply

Fast 50 ns Data Load Tim e, All Tem peratures

Pin-for-Pin Replacem ent for PM-7226 and AD7226,

nal load driving capability.

T he DAC8426 contains four 8-bit voltage-output CMOS D/A

converters on a single chip. A 10 V output bandgap reference

sets the output full-scale voltage. T he circuit also includes four

input latches and interface control logic.

One of the four latches, selected by the address inputs, is loaded

from the 8-bit data bus input when the write strobe is active

low. All digital inputs are T T L/CMOS (5 V) compatible. T he

on-board amplifiers can drive up to 10 mA from either a single

or dual supply. T he on-board reference that is always connected

to the internal DACs has 5 mA available to drive external devices.

APPLICATIONS

Level and Threshold Setting

Its compact size, low power, and economical cost-per-channel,

make the DAC8426 attractive for applications requiring mul-

tiple D/A converters without sacrificing circuit-board space. Sys-

tem reliability is also increased due to reduced parts count.

PMI’s advanced oxide-based, silicon-gate, CMOS process al-

lows the DAC8426’s analog and digital circuitry to be manufac-

tured on the same chip. T his, coupled with PMI’s highly stable

thin-film R-2R resistor ladder, aids in matching and tempera-

ture tracking between DACs.

GENERAL D ESCRIP TIO N

T he DAC8426 is a complete quad voltage output D/A converter

with internal reference. T his product fits directly into any exist-

ing 7226 socket where the user currently has a 10 V external

reference. T he external reference is no longer necessary. T he

internal reference of the DAC8426 is laser-trimmed to ±0.4%
