NJU72040
Ground Referenced Stereo Headphone Amplifier
GENERAL DESCRIPTION
The NJU72040 is an audio headphone amplifier .
Ground-referenced outputs eliminate output coupling
capacitor. The pop noise suppression circuit removes a pop
noise at the power-on and power-off.
It is suitable for audio headphone amplifer application
