I'm working with a STM32L053R8 and I want to use some ADC pins. I have a doubt about the input voltage range.
Does the ADC have an independent power supply?
Which is the input voltage range of the ADC?
Let's suppose that I am supplying the STM with 3.3 V, and I am using 12 bits from the ADC.
That means that...?
- The input voltage range goes from 0V to 3.3V?
- The step-quantization is 3.3/(2^12-1)?
