NTE941S
Integrated Circuit
Operational Amplifier
Description:
The NTE941S is a general purpose operational amplifier in a 7–Lead SIP type package and offers
many features which make its 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.
