Features:
  • ・Provides Surround and Bass Boost with the Soft-switching feature to reduce the shock
        sound at switching (BD3401KS・
    ・Provides a specialized power supply terminal in a digital circuit ,in order to set and
        maintain the state inside the IC by the minute stand-by current.
    ・Built-in preamplifier for cassette recording/playing allows for minimal external
        components,feeling up board space.
    ・Arranges all I/O terminals to a single point and allows easy PCB routing.
    ・Volume and Tone implemented with a resistance ladder circuit;achieving high
        performance with low noise and low distortion.
    ・Enargy-saving design resulting in low current consumption,by utilizing the BiCOMS
        process.It has the advantage in quality over the scaling down the power heat
        control of the     internal regulators.
