UA748CN
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.
Short-circuit protection
Offset voltage null capability
Large common-mode and differential voltage
ranges
Low power consumption
No latch-up
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 dissipation
permits high voltage operation and simplifies pack-
aging in full-temperature range systems.
