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.
