Note:

Depending on the employed REC / PB head and test tape characteristics, there is a rare case that

the REC-EQ characteristics of this LSI can not be matched to the required characteristics because of

built-in resistors which determined the REC-EQ parameters in this case, please inquire the

responsible agent because the adjustment built-in resistor is necessary.

Note: The HA12226F/HA12227F became single power supply for the HA12215F and deleted metal

correspondence. The HA12227F is not built-in Dolby B-NR.

Other characteristic aspects are similar as the HA12215F.
