NTE948 & NTE948SM
Integrated Circuit
Quad Operational Amplifier
Description:
The NTE948 (14Lead DIP) and NTE948SM (SOIC14) consists of four independent, high gain, in-
ternally compensated, low power operational amplifiers which have been designed to provide func-
tional characteristics identical to those of the familiar 741 operational amplifier.
Features:
Low Supply Current Drain
Class AB Output Stage No Crossover Distortion
Low Input Offset Voltage
Low Input Offset Current
Low Input Bias Current
High Degree of Isolation Between Amplifiers
Overload Protection for Inputs and Outputs
Available in 14Lead DIP (NTE948) and Surface Mount (NTE948SM)

Note 1. Any of the amplifier outputs can be shorted to ground indefinitely; however, more than one
should not be simultaneously shorted as the maximum junction temperature will be exceeded.
Note 2. The maximum power dissipation for these devices must be derated at elevated tempera-
tures and is dicated by T
