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.
