Integrated Circuit
Audio Power Amp, 2 Watt
Description:
The NTE1117 is a monolithic integrated audio amplifier in a 14–Lead DIP type plastic package de-
signed for use as a low frequency class B amplifier with a wide range of supply voltage of 3V to 16V.
Features:
D Minimum Working Voltage of 3V
D Low Quiescent Current
D Low Number of External Components
D Good Ripple Rejection
D No Cross–Over Distortion
D Output Power:
PO = 2W at 12V – 8Ω
PO = 1.6W at 9V – 4Ω
PO = 1.2W at 9V – 8Ω
