Subject: Maximum analog input voltage 

In principle the numbers in the manual are correct. But they relate to pulses of a certain length, because the input protection only works for DC voltage and for pulses which are not too long. Since we could not write this all on the label of the board, we decided to put there 100% safe value as a "warning" to people, meaning that if pulses are above 2.5V, they should look into the manual and read the details.

Dear all,

I have been wondering what the maximum analog input voltage for the DRS4 V5 evaluation board is. It came with a sticker indicating that it is "2.5V pk Max". On the other hand, when checking the manual (https://www.psi.ch/drs/DocumentationEN/manual_rev50.pdf), it says maximum allowed is 10V DC or even 30V for short pulses. I foresee an application where I cannot make sure that pulses stay below 2.5V, so the correct value will be quite important for me.

Best,
Julian
