Hi, team.

I have got the question from my customer about PCA9306.

So, please tell me about below question.

＜Question＞
For the description of 9.2.2.1 on P11 of datasheet,

it is recommended that 100pF for the capacitance connected to VREF2,

but is there a problem if a capacitance of 0.01uF is connected?

Best regards,

Hey Masumi-san,

"is there a problem if a capacitance of 0.01uF is connected?"

This is okay, the capacitance on this pin is meant to keep the reference voltage stable. With 0.01uF the device still works no problem.

Thanks,

-Bobby
