General Description

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 turn 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.
