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.
Features:
D No Frequency Compensation Required
D Short−Circuit Protection
D Wide Common−Mode and Differential Voltage Ranges
D Low−Power Consumption
D No Latch−Up
D Balanced Offset Null
D Choice of Package Types:
NTE947: 10−Lead Metal Can
NTE947D: 14−Lead DIP

Note 1. NTE947 is a discontinued device and no longer available.
Note 2. 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 3. For supply voltages less than ±15V, the absolute maximum input voltage is equal to the supply
voltage.
