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. 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 s upply v oltages l ess t han ±15V, the a bsolute m aximum input voltage is e qual t o t he s upply
voltage.
