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
amplif i e rs, phonograph preamplifiers, and FM stereo receivers.

An i ntegral v oltage r egulator e lim inates the n eed f or a udio o r R F d ecoupling. Internal f eedback r esi stors
are provided for NAB equalization.
