Eigenschaften:
・ Built-in differential input selector that can make various combination of single-ended / differential input.・ Reduce switching noise by using advanced switch circuit
・ Built-in ground isolation amplifier inputs, ideal for external stereo input.
・ Decrease the number of external components by built-in 2nd-order anti-aliasing filter
・ Decrease the number of external components by built-in 2-band equalizer filter and loudness filter.
・ A PCB area can be reduced and PCB layouts become easy thanks to that signal flow is gathered to one direction by arrangement of input and output left side and right side separately.
・ It is possible to control by 3.3V / 5V for I²C BUS serial controller.
