NJU7085 Series
High-Power & Low-Voltage Stereo Audio Power Amplifier with 3D Surround

Download Datasheet

  • Description

    The NJU7085 is a stereo audio power amplifier with surround sound technology for portable applications. No external coupling capacitors are required because of the differential outputs. The closed loop gain is adjusted by two external resistors. And the standby mode control reduces the supply current. The NJU7085 contains pop & click noise protection circuitry which eliminates noises during turn-on and turn-off transitions and RF rectification canceling circuitry. It is suitable for portable telephone, wireless telephone, button telephone, and other speaker amplifier applications.
