DUAL AUDIO POWER AMPLIFIER
■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE
The NJW1105 is a dual audio amplifier which supplies 2.4W
( 1.2W/channel ) to 8Ω loads at 5V.Its features are wide operating
voltage range from 4V to 12V and low consumption output by
Bi-MOS technology.
The NJW1105 is suitable for speaker amplifier required high
output power,such as personal computers,camcorders,and others.It
includes thermally protected and mute on/off circuit.
