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.
