Yeah, I would not load that pin; just throw an unity gain amplifier at it and you should be good. Ok that makes sense to me. It felt a bit hack to put a load on it :). If the value I measure at this pin without a load does not match the value burned into the efuse that sets vref is there a way to o...

I want to use ADC2 VREF as the voltage source for a divider circuit that I will then read with ADC1. I use the following to accomplish the routing of the vref to the gpio. esp_err_t status = adc2_vref_to_gpio( GPIO_NUM_25); When this pin is floating the voltmeter reads it at 1.112 but reads at 1.102...
