DESCRIPTION

The UA748 is a general purpose operational am-

plifier built on a single silicon chip. The resulting

close match and tight thermal coupling gives low

offsets and temperature drift as well as fast recov-

ery from thermal transients.

The unity-gain compensation specified makes the

circuit stable for all feedback configurations, even

with capacitive loads. However, it is possible to

optimize compensation for best high frequency

performance at any gain. The low power dissipa-

tion permits high voltage operation and simplifies

packaging in full-temperature range systems.
