NTE976 Integrated Circuit Operational Amplifier Description: The NTE976 is a general purpose operational amplifier with the necessary frequency compensation built into a single 8Lead DIP type package. Advanced processing techniques make the input cur- rents a factor of ten lower than industry standards like the NTE909. Yet, it is a direct plugin replace- ment for the NTE909 and the NTE941M. This device provides better accuracy and lower noise in high impedance circuitry. The low input cur- rents also make it particularly well suited for long interval integrators or timers, sample and hold cir- cuits, 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.
