Re: Digital To Analogue Converter Characteristics

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
Best regards

External Voltage Reference Pin

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
