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.
