Hi,

Is my understanding correct that the uC should be connected to OPT3101 as below ?

Kato,

Are you just asking which supply line to power the uC off of assuming it runs at the same voltage? If so, yes uC should run off of IOVDD. You can also refer to our EVM schematics posted online which shows an example of this since the way you have wired will work if using internal or external regulator.

Best,

Alex

Hi Alex-san,

Thank you for the explanation.

Could you please double-check the following the supply network if using OPT3101 with off-chip 1.8V regulator ?

Best regards,
Kato
