NTE976
Integrated Circuit
Operational Amplifier
Description:
The NTE976 is a general purpose operational amplifier with the necessary frequency compensation
built into a single 8–Lead DIP type package. Advanced processing techniques make the input currents a factor of ten lower than industry standards like the NTE909. Yet, it is a direct plug–in replacement for the NTE909 and the NTE941M.
This device provides better accuracy and lower noise in high impedance circuitry. The low input currents also make it particularly well suited for long interval integrators or timers, sample and hold circuits, and low frequency waveform generators. Further, replacing circuits where matched transistor
pairs buffer the inputs of conventional IC op amps, the NTE976 can give lower offset voltage and drift
at a lower cost.

Note 1. The maximum junction temperature of the NTE976 is +100°C. The thermal resistance
junction to ambient is +100°C/W.
Note 2. For supply voltages less than –15V, the absolute maximum input voltage is equal to the
supply voltage.
