Hello, all
Now I am referring PGA308 User's Guide Literature (SBOU069B), then would like to ask you regarding RISO resister.
We would like to have 1W communication line from PGA308 to MCU, then understood this resistance for 1W is defined as 100ohm.
However, in order to protect external components, we need to select more than 100ohm resistance.
Please let us know whether the resistance for RISO could exceed 100ohm or not.
We thank you in advance for your information.
Best regards,
