Quad 8-Bit Voltage Out CMOS DAC Complete with Internal 10 V Reference
REV.C
Quad 8-Bit Voltage Out CMOS DAC
Complete with Internal 10 V Reference
GENERAL DESCRIPTIONThe DAC8426 is a complete quad voltage output D/A converter
with internal reference. This product fits directly into any exist-
ing 7226 socket where the user currently has a 10 V external
reference. The external reference is no longer necessary. The
internal reference of the DAC8426 is laser-trimmed to ±0.4%
FEATURES
No Adjustments Required, Total Error 61 LSB Max
Over Temperature
Four Voltage-Output DACs on a Single Chip
Internal 10 V Bandgap Reference
Operates from Single 115 V Supply
Fast 50 ns Data Load Time, All Temperatures
Pin-for-Pin Replacement for PM-7226 and AD7226,

APPLICATIONS
Process Controls
Multichannel Microprocessor Controlled:
System Calibration
Op Amp Offset and Gain Adjust
Level and Threshold Settingoffering a 25 ppm/°C temperature coefficient and 5 mA of exter-
nal load driving capability.
The 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. The 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 TTL/CMOS (5 V) compatible. The
on-board amplifiers can drive up to 10 mA from either a single
or dual supply. The 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. This, coupled with PMI’s highly stable
thin-film R-2R resistor ladder, aids in matching and tempera-
ture tracking between DACs.

permanent damage may occur on unprotected units from
high-energy electrostatic fields. Keep units in conductive
foam at all times until ready to use.Do not insert this device into powered sockets. Remove
power before insertion or removal.Stresses above those listed under “Absolute Maximum Rat-

Electrical tests are performed at wafer probe to the limits shown. Due to variations in assembly methods and normal yield loss, yield after packaging is not guaranteed
for standard product dice. Consult factory to negotiate specifications based on dice lot qualifications through sample lot assembly and testing.
