NTE1116
Integrated Circuit
Audio Power Amplifier, 5W
Description:
The NTE1116 is a monolithic integrated circuit designed for use as a low frequency class B amplifier.
The external cooling tabs enable 2.5 watts of output power to be achieved without the use of an external heat sink and 5 watts of output power using a small area of the P.C. board copper as a heat sink.
