Single Power Supply Sound Processors with Built-in Pre-amp for Tape Recording and Playback - BD3402KS2

ROHM sound processors integrate a five-input selector, electronic volume control, 2- or 3-band equalizer, and a cassette tape recording and playback amps on a single chip and feature low distortion (0.0013% Typ.), making them ideally suited for use in mini-component and portable audio systems. In addition, they offer compatibility with single power supplies.

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.
