NTE941M & NTE941SM
Integrated Circuit
Operational Amplifier
Description:
The NTE941M and NTE941SM (Surface Mount) are general purpose operational amplifiers in
8–Lead DIP type packages and offer many features which make their application nearly foolproof:
overload protection on the input and output, no latch–up when the common mode range is exceeded,
as well as freedom from oscillators.
