NTE7088
Integrated Circuit
Audio Power Amplifier,
18 Watt BTL x 2 Channel
Description:
The NTE7088 is an integrated circuit in a 17–Lead Staggered SIP type package designed for car audio applications. This device has two built–in channels to reduce the characteristic difference betwee
Left and Right channels. In addition, the functions of stand–by and muting, and a variety of protection
circuits are included.
