Hello guys, i have some doubt about the power specification of jack 3.5mm audio output. I was searching in google and i got some links like this:
https://raspberrypi.stackexchange.com/q ... dio-output
viewtopic.php?t=76636
I am not sure if this information is official, can someone help me with that?
Thanks for read!
Regards.

Re: Question about Audio Jack spec from Raspberry Pi 3
Almost nothing there is official, and things have moved on in the intervening six years.
However, if you look at the reduced schematic at https://www.raspberrypi.org/documentati ... educed.pdf you'll see that it's driven from an amplifier, powered from 3v3 and gnd.
That means it cannot produce more than 3v3 p-p.
That's followed by a low-pass filter divider chain, and if you work out its characteristics you find that it's, as I said all those eons ago,
