Hi,

The Renesas X9250 integrated four digitally controlled potentiometers.
On each potentiometer, the X9250T has a 100 kOhms total resistance and
the X9250U has a 50 kOhms total resistance.

Compare to the previous iteration

This v2 series uses a define for the X9250 ID value.

Best regards,
Herve Codina
