STM32F303 Analog Comparator PINOUT

T B
Associate II

Hello!

I is allowed to use the same PIN for the COMP and the ADC?

I use the analog comparator as fast and software free PWM break input and I would like the measure the input with a ADC. I have tried it out and it was working. There was a small distortion from the sample and hold capacitor, but I can live with this.

Second Question:

Can I connect the DAC to the COMP only internally or do I need an PIN?

For Example I would like the use PA4 as ADC2_IN1 while DAC_OUT1 is used as

Input[-] for COMP1.
