NTE983

Integrated Circuit

Low Noise Dual Preamp

Description:

The NTE983 is a linear monolithic integrated circuit in a 14–Lead DIP type package designed for use

with low–level signals in low–noise applications. This device offers outstanding value, performance,

and reliability in both consumer and industrial products such as stereo tape players, microphone

amplifiers, phonograph preamplifiers, and FM stereo receivers.

An integral voltage regulator eliminates the need for audio or RF decoupling. Internal feedback resistors

are provided for NAB equalization.
