NTE948 & NTE948SM
Integrated Circuit
Quad Operational Amplifier
Description:
The NTE948 (14–Lead DIP) and NTE948SM (SOIC–14) 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 14–Lead 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 TJ(MAX), RthJA, and the ambient temperature, TA. The maximum avail-
able power dissipation at any temperature is PD = (TJ(MAX) – TA)/RthJA or the 25°C PD(MAX),
which ever is less.
