NTE941
Integrated Circuit
Operational Amplifier
Description:
The NTE941 is a general purpose operational amplifier in an 8–Lead TO5 Metal Can 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.

Note 1. For operation at elevated temperatures, these devices must be derated based on thermal
resistance, and TJ Max (TJ = TA + (RthJA PD).
Note 2. For supply voltage less than ±15V, the absolute maximum input voltage is equal to the supply
voltage.
