NJM2149 LOW VOLTAGE AUDIO POWER AMPLIFIERThe 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 resistorsand 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 reductioncompared with NJM2135. It is suitable for portable telephone Wireless telephonebutton telephoneand other speaker Amplifier applications.
