GENERAL DESCRIPTION
The DAC8408 is a monolithic quad 8-bit multiplying digital-to-
analog CMOS converter. Each DAC has its own reference input,
feedback resistor, and onboard data latches that feature
read/write capability. The readback function serves as memory
for those systems requiring self-diagnostics.
FEATURES
Four DACs in a 28 Pin, 0.6 Inch Wide DIP or 28-Pin JEDEC
Guaranteed Monotonic
DACs Matched to Within 1%
Microprocessor Compatible
Read/Write Capability (with Memory)
TTL/CMOS Compatible
Four-Quadrant Multiplication
Single-Supply Operation (+5 V)
Low Power Consumption
Latch-Up Resistant
Available In Die Form
APPLICATIONS
Voltage Set Points in Automatic Test Equipment
Systems Requiring Data Access for Self-Diagnostics
Industrial Automation
Multichannel Microprocessor-Controlled Systems
Digitally Controlled Op Amp Offset Adjustment
Process Control
Digital Attenuators

A common 8-bit TTL/CMOS compatible input port is used to
load data into any of the four DAC data-latches. Control lines
DS1, DS2, and A/B determine which DAC will accept data.
Data loading is similar to that of a RAMs write cycle. Data can
be read back onto the same data bus with control line R/W. The
DAC8408 is bus compatible with most 8-bit microprocessors,
including the 6800, 8080, 8085, and Z80. The DAC8408 oper-
ates on a single +5 volt supply and dissipates less than 20 mW.
The DAC8408 is manufactured using PMI’s highly stable,
thin-film resistors on an advanced oxide-isolated, silicon-gate,
CMOS process. PMI’s improved latch-up resistant design elimi-
nates the need for external protective Schottky diodes.
