Can powering the ADC on and off often wear it down?

Hi! In order to save energy we want to power the ADC off when we don't use it with `adc_power_off`. However, we use the ADC every 100 ms, which means that the ADC will be powered off and on 10 times every second all the time. Is this ok, or does the ADC have a wear limit for how many times it can be turned on and off?

Stuff in the ESP32 silicon generally doesn't have a wear limit we're aware of. Using some heuristics: there's many thousands transistors in the ESP chips that get turned off and on millions of times per second; I can't imagine why the ADC transistors would be special in that respect.

Great, thanks for the quick reply!
