NTE894M & NTE894SM
Integrated Circuit
Low Noise Operational Amplifier
Description:
The NTE891M and NTE891SM are single, high–performance, low noise operational amplifiers.
Compared to other operational amplifier, these devices show better noise performance, improved
output drive capability and considerably higher small–signal 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.
Features:
D Small–Signal Bandwidth
D Large Supply Voltage Range
D Available in 8–Lead Mini DIP (NTE894M) and Surface Mount SOIC–8 (NTE894SM)
Applications:
D Audio Equipment
D Instrumentation and Control Circuits
D Telephone Channel Amplifiers
D Medical Equipment

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 ±10mA.
Note 2. For operation at elevated temperature, derate packages based on the following junction–to–
ambient thermal resistance: NTE894M 105°C/W; NTE894SM 160°C/W.
Note 3. Output may be shorted to GND at VS = 15V, TA = +25°C. Temperature and/or supply voltages
must be limited to ensure dissipation rating is not exceeded.
