・Low noise (5μVrms(TYP.)) and low distortion(0.002% (TYP.)).
・Built-in simple surround. Furthermore, it can constitute good surround of sound image
    normal position with an external part.
・It can constitute a bass boost or output gain with an external part.
・When the volume setting exchanging, it can use a volume terminal as a microphone input
    because there is not an impedance change of a volume terminal.
・Bi-CMOS process is suitable for the design of low current and low energy. And it provides
