Hello, does any one know what is the DAC maximum output value? And for ADC what is the maximum input value?
I do not see those in the datasheets.
This is for ESP-WROOM-32 and ESP-WROOM-32U

Thank you

Thank you, then how to access the internal voltage reference and what is that value? Also what is the +/- voltage range for the analog channels inputs?

Hello, I want to use an external voltage reference of 2.5V for ADC, but I have not found in the documentation what the pins are for connecting this device. Any help please? Also what changes in registers are required to use that external Vref? Thank you
