NJU72013
2Vrms Ground Referenced Stereo Line Amplifier with LPF
Q GENERAL DESCRIPTION The NJU72013 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.
