On the datasheet for the SparkFun Qwiic 12 Bit ADC ‐ 4 Channel (ADS1015) at...
https://mm.digikey.com/Volume0/opasdata ... 34_Web.pdf

It says the operating voltage is 2 volts to 5.5 volts.
Elsewhere it says using the Qwiic connect the operating voltage is 3.3 volts.

My Questions:

• 1 - if I bring power to the board via the screw terminals can I use a 5 volt supply...
  or must I buy a "buck" converter to have it stepped down to 3.3 volts?

• 2 - What is the range of the analog voltage going to any of the four a/d screw terminals?

Thanks for any help.

Eh, it's a mixed bag - see this entire section https://learn.sparkfun.com/tutorials/qw ... e-overview which can walk you through the different configurations (some require stepped-down, some not)
