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.
Features:
D Very High Operating Voltage Range
D DMOS Power Stage
D High Output Power (Up To 100W Music Power)
D Muting/Stand - By Functions
D No Switch ON/OFF Noise
D No Boucherot Cells
D Very Low Distortion

Note 1. Music Power is the maximum power which the amplifier is capable of producing across the
rated load resistance (regardless of non linearity) 1sec after the application of a sinusoidal
input signal of frequency 1kHz.
Note 2. Limited by the maximum allowable current.
