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%

C temperature coefficient and 5 mA of exter-
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.
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.
