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.

note:1.The CD terminal(1pin) should connect High level(>2.0V), when NJM2149 is active.
The standby mode, when the CD terminal is Low level(<0.8V).
2.To add the C1 and C2 capacitor, the power-supply-rejection-ratio will be improved.
When C1 is large value, C2 will be unnecessary.
3.The power-up time depend on the C1 and C2 capacitor.
4.The input current of CD terminal is as shown below figure.
