NTE947 & NTE947D
Integrated Circuit
Dual Operational Amplifier
Description:
The NTE947 and NTE947D are general purpose dual operational amplifiers in a 10Lead Metal Can
and 14Lead 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, junctiontoambient, or +45
C/W, junctiontocase. The thermal resistance of
the NTE947D is +100
C, junctiontoambient.
Note 2. For supply voltages less than
15V, the absolute maximum input voltage is equal to the supply
voltage.
