■GENERAL DESCRPTION
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.
