NTE7118
Integrated Circuit
Audio Power Amplifier, 50W
Description:
The NTE7118 integrated circuit is a hi–fi power amplifier in a 9–Lead SIP type package designed for
use as a building block in radio, TV, and other audio applications. The high performance of the IC
meets the requirements of digital sources (e.g. Compact Disc equipment).
The NTE7118 is totally protected, the two output transistors both having tthermal and SOAR protec-
tion. This device also has a mute function that can be arranged for a period after power–on with a
delay time fixed by external components.
The NTE7118 device is intended for symmetrical power supplies but an asymmetrical supply may
also be used.
