Integrated Circuit
FM Stereo Multiplex Decoder
Description:
The NTE722 is a monolithic FM Stereo Multiplex Decoder System in a 14–Lead 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 line–operated and automotive FM stereo multiplex applications.
Features:
45dB Channel Separation
55dB Storcast Rejection without SCA Filters
High Current Stereo Indicator Lamp Driver
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 turn–on
of the Stereo Indicator Lamp is 500mA.
