ESP32-C3-Mini-1U ADC0 question.

[MangledBanana]

Hey,

Since all the ADCs on ADC0 are multiplexed to the one SAR, is the offset and gain the same across all the ADC channels?

The reason I ask is that I'm working on a PCB that's going to use 4/5 of the ADCs on ADC0. I was thinking I could add a simple circuit that would calculate the offset and gain of ADC0 at boot to calibrate the other four channels.

Hope my question was clear!

Sorry, I meant ADC1 obviously. I didn't realise the channels start counting at 1.
