NTE941
Integrated Circuit
Operational Amplifier
Description:
The NTE941 is a general purpose operational amplifier in an 8Lead TO5 Metal Can type package
and offers many features which make its application nearly foolproof: overload protection on the input
and output, no latchup when the common mode range is exceeded, as well as freedom from oscilla-
tors.
