NTE NTE949

NTE949
Integrated Circuit
Dual Audio Operational Amplifier/Preamplifier
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 of loads to be employed for general purpose applications
from DC to 10MHz, where two high performance operational amplifiers are required. In addition, the
outputs may be wired–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:
D Single or Dual Supply Operation
D Low Power Consumption
D High Gain: 25,000 V/V
D Large Common Mode Range: +11V, –13V
D Excellent Gain Stability vs. Supply Voltage
D No Latch–Up
D Output Short Circuit Protected
