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 Absolute Maximum Ratings: Supply Voltage, VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ±18V Power Dissipation (Note 1), PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 800mW Differential Input Voltage, VID . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ±30V Common–Mode Input Swing Voltage (Note 2), VICR . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ±15V Output Short–Circuit Duration, tOS . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

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.
