NTE7165 Integrated Circuit DMOS Audio Amplifier, 100W, for Self - Powered Loudspeakers Description: The NTE7165 is a monolithic integrated circuit in a 15 - Lead Staggered SIP type package designed for use as an audio class AB amplifier in Hi - Fi field applications (Home Stereo, self - powered loudspeakers, Top - Class TV). Thanks to the wide voltage range and to the high output current cazpability it is able to supply the highest power into both 4Ω and 8Ω loads even in the presence of poor supply regulation, with high Supply Voltage Rejection. The built - in muting function with turn- on delay simplifies the remote operation avoiding switching ON/OFF noises.
