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
