NTE947 & NTE947D
Integrated Circuit
Dual Operational Amplifier
Description:
The NTE947 and NTE947D are general purpose dual operational amplifiers in a 10–Lead Metal Can
and 14–Lead DIP type packages respectively. These two amplifiers share a common bias network
and power supply leads. Otherwise, their operation is completely independent.

Note 1. The maximum junction temperature of the NTE947 and NTE947D is 100°C. For operating
at elevated temperatures, the NTE947 must be derated based on a thermal resistance of
+150°C/W, junction–to–ambient, or +45°C/W, junction–to–case. The thermal resistance of
the NTE947D is +100°C, junction–to–ambient.
Note 2. For supply voltages less than
±15V,
the absolute maximum input voltage is equal to the supply
voltage.
