Block Diagram
This IC can be constructed for simple system which has little external parts by used the head serving both
as Recording and Play back because of REC return SW built-in.
With output Hi-Z of REC-EQ and input muting, this IC is realized not only REC mute attenuation
sufficiently but reducing pop noise in REC muting.
Note:
Referring to Parallel Data Format also.
