I've got an explorer phat and an enviro phat. Both have analog inputs using the ADS1015. The explorer phat docs say max 5v, while the enviro docs say 3.3v (and includes a whole section on 5v to 3.3v conversion).
The ADS1015 datasheet says anything up to 5v is ok.
I guess you only need to use 3.3v for those sensors that can't handle 5v, and you might need the max voltage to calculate the value being read.
The enviro phat hasn't blown up (as far as I can tell) when I accidentally used the very convenient 5v pin as power for a 10k pot to simulate an analogue sensor. I can read raw 0-4096 just fine on either phat with 5v inputs.
I am a little bit bemused by the different info, for the phats.
Is it okay to use 5v with the enviro phat analogues or not?
