High-Power and Low-Voltage Audio Power Amplifier

Manufacturer's part number :


Manufacturer New Japan Radio

New Japan Radio

Description :

The NJU7089 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 NJU7089 improves high output power compared with other amplifier.
