Description

The UA748 is a general purpose operational amplifier built on a single silicon chip. The resulting close match and tight thermal coupling gives low offsets and temperature drift as well as fast recovery fromthermal 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 UA748 stable for all feedback configurations, even with capacitive loads. However, it is possible to optimize compensation for best high frequency performanceatanygain. The low powerdissipation of UA748 permits high voltage operation and simplifies packaging in full-temperature range systems.
