NTE894M & NTE894SM
Integrated Circuit
Low Noise
Operational Amplifier
Description:
The NTE891M and NTE891SM are single, high鈥損erformance, low noise operational amplifiers.
Compared to other operational amplifier, these devices show better noise performance, improved
output drive capability and considerably higher small鈥搒ignal and power bandwidths.
This makes the devices especially suitable for applications in high quality and professional audio
equipment, in instrumentation and control circuits and telephone channel amplifiers. The OP amps
are internally compensated for gain equal to, or higher than, three.

Note 1. Diodes protect the inputs against over voltage. Therefore, unless current limiting resistors
are used, large currents will flow if the differential input voltage exceeds 0.6V. maximum cur-
rent should be limited to
鹵10mA.
Note 2. For operation at elevated temperature, derate packages based on the following junction鈥搕o鈥?/div>
ambient thermal resistance: NTE894M 105擄C/W; NTE894SM 160擄C/W.
