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.
