Features:
・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
terminal
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
more quality for small scale regulator and heat in a set.
・The package of this IC is SSOP-B28. It gathers a sound input terminals, sound output
terminals respectively and it arranges them, to be arranging facilitates the
laying-out of PCB pattern and reduces PCB area to one-way in the flow of the
signal.
