Integrated Circuit
Quad Operational Amplifier
Description:
The NTE997 is a monolithic quad operational amplifier in a 14–Lead DIP type package consisting of
four independent high gain, internally compensated operational amplifiers. The specifically designed
low noise input transistors allow the NTE997 to be used in low noise signal processing applications
such as audio preamplifiers and signal conditioners. The simplified output stage completely elimi-
nates crossover distortion under any load conditions, has large source and sink capacity, and is short–
circuit protected. A novel current source stabilizes output parameters over a wide power supply volt-
age range.
Features:
D Unity Gain Bandwidth: 3MHz
D Continuous Short Circuit Protection
D No Frequency Compensation Required
D No Latch–Up
D Large Common Mode and Differential Voltage Ranges
D Parameter Tracking Over Temperature Range
D Gain and Phase Match Between Amplifiers

Note 1. For supply voltage less than ±15V, the absolute maximum input voltage is equal to the supply
voltage.
Note 2. Short–circuit may be to GND, one amplifier only. I_SC = 45mA (Typical).
