NJU72015
2Vrms Ground Referenced Stereo Line Amplifier
GENERAL DESCRIPTION
The NJU72015 is an audio line Amplifier . It can swing
2Vrms (5.6V peak-to-peak) signal at 3.3V operating voltage.
Ground-referenced outputs eliminate output coupling
capacitor. It contains differential input.
The pop noise suppression circuit removes a pop noise at
the power-on and power-off.
