NJU7085 - High-Power & Low-Voltage Stereo Audio Power Amplifier

General 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.

NJU7085 High-Power & Low-Voltage Stereo Audio Power Amplifier with 3D Surround ■GENERAL 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. ■ PACKAGE OUTLINE NJU7085SF7 ■ APPLICATION • Portable DVD/TV • Cradle Speaker • Mobile-phone/PHS NJU7085V ■FEATURES • Operating Voltage V+=2.8 to 5.5V • Operating Current IDD1=4.6 mA typ.
