NJU72014

NJU72014 2Vrms Ground Referenced Stereo Line Amplifier with LPF Q GENERAL DESCRIPTION The NJU72014 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.
