Integrated Circuit Dual Audio Operational Amplifier/Preamplifier
8-PIN METAL CAN

Description:

The NTE949 consists of two identical high gain OP amps constructed on a single 8-Lead Metal Can type package. These three-stage amplifiers use Class A PNP transistor output stages with uncommitted collectors. This enables a variety od loads to be employed for general purpose applications from DC to 10MHz, where two high performance operationa amplifiers are required. In addition, the outputs may be wored-OR for use as a dual comparator or they may function as diodes in low threshold rectifying circuits such as absolute value amplifiers and peak detectors.

Features:

• Single or Dual Supply Operation
• Low Power Consumption
• High Gain:  25,000 V/V
• Large Common Mode Range:  +11V, -13V
• Excellent Gain Stability vs. Supply Voltage
• No Latch-Up
• Output Short Circuit Protected

Absolute Maximum Ratings:

Supply Voltage, V+, V-		±18V
Internal Power Dissipation (TA = +70°C), PD		500mW
Derate Above 70°C		6.8mW/°C
Input Differential Voltage, VID		±5V
Input Common-Mode Range (Note 1), VICR		±15V
Operating Temperature Range, Topr		0° to +70°C
Storage Temperature Range, Tstg		-65° to +150°C
Lead Temperature (During Soldering, 60sec max), TL		+300°C
Output Short-Circuit Duration (TA = +25°C, Note 2), tOS		30sec

Note 1.	For supply voltages less than ±15V, the absolute maximum input voltage is equal to the supply voltage.
Note 2.	Short circuit may be to GND oer either supply.
