Description
NTE1056 Integrated Circuit FM Stereo Multiplex Demodulator
Description: The NTE1056 is a monolithic integrated circuit FM multiplex stereo demodulator designed for use in FM stereos, phonographs and radio receivers.
A multiplex stereo demodulator circuit generally conwww.
DataSheet4U.
com sists of four main circuits, a composite signal amplifier, 19KHz pilot signal filter, 38KHz subcarrier generator and either a matrix or a switching circuit which seperates the composite signal into the right and left audio channels.
In addition to these circuits, an automatic stereo−monaural switching circuit, stereo signal indicator circuit, muting circuit, separation control circuit and SCA circuit are also included as supplemental circuits.
The NTE 1056 is designed to include both main stereo demodulator circuits and supplemental circuits on a common monolithic substrate, and is supplied in a 14 lead DIP.
Features: D Separation Control D On, Off Level Control D Monoaural Muting D Either Positive or Negative Grounding are Available Absolute Maximum Ratings: (TA = +25°C unless otherwise specified) Supply Voltage, V2−12 .
