Hello TI teams and forum users.
Firstly hope all is doing well.
We are finishing our PCB board using multiple OPA818. First as TIA and others as classic opamp.
We amplify SiPM photodiode which consist of current pulse of 500ns.
On PCB layout the datasheet recommend to don't have any plane under V- and Vout of all amplifier.
Do you confirm we have to remove all plane under ? Also the outter one on the oposite side ? And not on the feedback pin ?
On 1 opamp we have a relative long track at the output (16mm) before the next first resistor (the 50 ohm of the next amplifier which contribute to the gain).
For this should we remove the plane under all the track or for exemple put a 0ohm resistor ?
Thanks you for your help,
Have a nice day,
Simon
