NTE15007

Integrated Circuit

TV Stereo Multiplexing Decoder

Description:

The NTE15007 is a bipolar integrated circuit is a 42–Lead DIP type package designed for use in TV
stereo multiplexing decoding, filters for stereo, and SAP (Separate Audio Program) demodulation
applications.

Features:

• Low number of external parts

• Excellent channel separation characteristics for stereo applications. Min. 46dB at 1kHz.

• Selection of individual modes of MAIN/SAP/BOTH.

• Direct driving mode for LED display.
