2Vrms Ground Referenced Stereo Line Amplifier with LPF

Download Datasheet

  • 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 thepower-on and power-off.It is suitable for audio line interface of audio equipment which does not have over 9V regulator.
