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.
