NTE722

Integrated Circuit

FM Stereo Multiplex Decoder

Description:

The NTE722 is a monolithic FM Stereo Multiplex Decoder System in a 14âLead DIP type package.

This integrated circuit demodulated a stereo multiplex signal into the right and left audio channels

while inherently suppressing SCA frequency components. Internal provision is made for driving an

external stereo mode indicator lamp. The excellent performance and wide supply range requirement

make the NTE722 suitable for all lineâoperated and automotive FM stereo multiplex applications.

Features:

D 45dB Channel Separation

D 55dB Storcast Rejection without SCA Filters

D High Current Stereo Indicator Lamp Driver

D Operation with 8V to 14V Supplies

Note 1. Power supply transients up to 22V are permissible for periods of 15 seconds. However, ex-

tended operation at voltages greater than 15V should be avoided as the maximum allowable

internal power dissipation for this device may be exceeded.

Note 2. Rating applies to steady state current. Maximum permissible surge current during turnâon

of the Stereo Indicator Lamp is 500mA.
