Thank you for your patronage.
I want 1.2 V in operational amplifier circuit.
so, I want to use VREFINT as 1.2V.
But I don't know how to use VREFINT. I don't know how to output VREFINT with Cube MX.
I am using STM32F334Nucleo.
Vrefint is an internal only reference voltage in your case.
Other MCUs have the VREF as external pin.
But you can find here specialised voltage references for your need.
>>>"But I don't know how to use VREFINT."
VREFINT can be readed form ADC1, ADC2 as a normal channel . Can be used also from internal comparators as negative input!!
Other use of VREFINT is to convert readed ADC values , to real voltages.
I love your posts. you bring the tech!
Thank you for your reply.
I'm sorry for my late reply.
I understand that Vrefint can not be used in my application, Other MCUs have the VREF as external pin.
Your reply is very helpful.
