NTE NTE7041 Datasheet
NTE7041
Integrated Circuit
Dual, Audio Power Amplifier, 22W BTL
Description:
The NTE7041 is an integrated circuit in a 17–Lead SIP type package designed for stereo audio use
in car stereo applications. This device has two built–in channels to reduce the characteristic difference between L and R channels. In addition, the NTE7041 contains stand–by and muting functions
and includes a variety of protection circuits.
