State of a DIO connected directly to an AIN affects another AIN's value

I have my t7 set up such that one FIO0 is set in output mode and connected directly to AIN0. I have a sensor on AIN1 and notice that whenever I toggle the state of FIO0 to low, this induces a +60mV change in the reading I get on AIN1 relative to when FIO0 is high. Is this expected behaviour?

What sort of signal is

What sort of signal is connected to AIN1?

If you remove your signal from AIN1 and instead jumper AIN1 to GND, do you still see the issue or does AIN1 read stead 0.0 regardless of what you do with FIO0?
