NTE7186
Integrated Circuit
DMOS Audio Amplifier, 100W
with Mute/Stand−By
Description:
The NTE7186 is a monolithic integrated circuit in a 15−Lead Staggered SIP type package, intended
for use as audio class AB amplifier in Hi−Fi field applications (Home Stereo, self powered loudspeak-
ers, Top class TV). Thanks to a wide voltage range and to the high out current capability it is able to
supply the highest power into both 4Ω and 8Ω loads. The built in muting function with turn on delay
simplifies the remote operation avoiding switching on−off noises.
