  • Description

    The NJU7084 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 SD pin permit power down with muting the input signal.The NJU7084 improves high output power compared with other amplifier. It is suitable for portable telephone,wireless telephone, button telephone, and other speaker amplifier applications.
