NJU7086 High-Power & Low-Voltage Stereo Audio Power Amplifier with Electronic Volume ■ PACKAGE OUTLINE ■GENERAL DESCRIPTION The NJU7086 is a stereo audio power amplifier designed for portable applications. Three input selector and an electronic volume are built into, and it contributes to a reduction of the number of external parts. 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 NJU7086 contains pop & click noise protection circuitry which eliminates noises during turn-on and turn-off transitions and RF rectification canceling circuitry.
