NJU72010
2Vrms Ground Referenced Stereo Line Amplifier with LPF
s GENERAL DESCRIPTION
The NJU72010 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. The pop noise suppression circuit removes a pop
noise at the power-on and power-off.
It is suitable for audio line interface of audio equipment
which does not have over 9V regulator.
