功能:
- 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.
