NJM2783  
Monaural Microphone Amplifier with ALC  
GENERAL DESCRIPTION  
PACKAGE OUTLINE  
The NJM2783 is a monaural microphone amplifier with  
auto level control function to avoid distortion due to clipping.  
The voltage gain and the limit level are adjustable by  
external resistors.  
It is suitable for mini component audio system, home  
audio system, karaoke and others.
