Integrated Circuit
22W BTL (2 x 11W) Stereo Power Amplifier
Description:
The NTE7119 integrated circuit is a class–B dual output amplifier in a 9–Lead SIP type package de-
signed primarily for use in car radio applications. This device contains two identical amplifiers with
differential input stages. The gain of each amplifier is fixed at 40dB.
