NTE858M
NTE858SM
Integrated Circuit
Dual, Low–Noise JFET–Input Operational Amplifier
Description:
The NTE858M and NTE858SM are dual, low–noise JFET input operational amplifiers combining two
state–of–the–art linear technologies on a single monolithic integrated circuit. Each internally com-
pensated operational amplifier has well matched high voltage JFET input devices for low input offset
voltage. The BIFET technology provides wide bandwidths and fast slew rates with low input bias cur-
rents, input offset currents, and supply currents. Moreover, these devices exhibit low–noise and low
harmonic distortion making them ideal for use in high–fidelity audio amplifier applications.

Note 1. The magnitude of the input voltage must not exceed the magnitude of the supply voltage or
15V, whichever is less.
Note 2. The output may be shorted to GND or either supply. Temperature and/or supply voltages
must be limited to ensure that power dissipation ratungs are not exceeded.
