Are you refering to this:
If so, some things are not clear to me, take a look of BA662 pinout:
than BA6110 pinout:
As I see we need to connect pin 1 of 6110 to pin 3 of 622. Next, control on 622 is pin1 and on 6110 pin4, all other are same, except bia which is no available in 622 as I see.
Or maybe schematic is correct if bias is used as one of inputs? Does anybody did ever do replace BA622 with 6110 like this?
