NTE941M & NTE941SMIntegrated Circuit

Operational Amplifier

Description:

The NTE941M and NTE941SM (Surface Mount) are general purpose operational amplifiers in

8Lead DIP type packages and offer many features which make their application nearly foolproofoverload protection on the input and output, no latchup when the common mode range is exceededas well as freedom from oscillators.

Note 1. For operation at elevated temperatures, these devices must be derated based on thermaresistance, and TJ Max (TJ = TA + (RthJA PD).

Note 2. For supply voltage less than 15V, the absolute maximum input voltage is equal to the supplyvoltage.
