NJM2149  
LOW VOLTAGE AUDIO POWER AMPLIFIER  
GENERAL DESCRPTION  
PACKAGE OUTLENE  
The NJM2149 is an audio power amplifier designed  
for telephone applications.  
No external coupling capacitors are required because  
of the differential outputs. The closed loop gain is  
adjusted by two external resistors, and a CD pin permit  
powering down with muting the input signal.  
The NJM2149 improves the tern noise reduction in  
switching Power Down mode and external high band  
noise reduction, compared with NJM2135.  
It is suitable for portable telephone , wireless  
telephone, button telephone, and other speaker  
amplifier applications.
