D AC9331-14
14-Bit Multiplying D AC
FEATURES
• 14-bit resolution and accuracy
• 2 and 4-quadrant multiplication
• Precision laser trimmed ladder
• Low power
• Single power supply operation
• Reliable
DESCRIPTION
The DA C9331-14 is a low cost 14-bit multiplying
digital-to-analog converter packaged in a unique
24-pin double DIP. Capable of 2 and 4-quadrant
multiplication, the unit is TTL/DTL and CM OS com-
patible with power consumption less than 30mW .
Power supply options include +5V (-1) or + 15V (-2).
Outstanding features of the DA C9331-14 include:
True 14-bit performance —Up to 14-bit resolution
and accuracy over the 0˚ to 70˚C operating range.
2 and 4-q uadrant m ultiplication —Reference input
range to ±25 volts.
Low pow er — CM OS technology provides less than
30mW total power dissipation — a real battery
saver.

Reliability plus — Packaged in a unique enclosure
t h at has undergone extensive environmental
testing during its development. The DA C9331-14 is
continuously monitored during all assembly and
test operations by our quality control organization.
Reliability is enhanced by batch-processed, preci-
sion laser-trimmed resistor networks fabricated in
our own facility. Similar to monoli thic circuits, the
networks are processed and functionally trimmed
to assure consistent performance.
