We are using ST32H743BI in an our project because of it having 3 of 16bits ADCs. But we can not reach resolution that project needed. I checked a simple project "STM32Cube_FW_H7_V1.3.0\Projects\STM32H743ZI-Nucleo\Examples\ADC\ADC_OverSampler" on NUC...

I am using STM32H743BI controller. I need to use backup RAM as nonvolatile ram. So I use external 3V battery and LSE 32.768 crystal for RTC. RTC works well but I can not use backup RAM. I use code like below;PWR->CR1 |= PWR_CR1_DBP;while(((PWR->CR1 &...

They don't have microcontroller that has 16bits ADCs

Thank you very much for your information. I did not read ENOB values. The given values for 2MSPS conversations but we are using 500 KSPS so the values must be better. However, we should not expect 16 bits resolutions.

There is 84 analogue channels over multiplexers to read and minimum 3 ADCs needed so using external ADCs will be very expensive solution. If ST32H743BI can not reach true 16bits resolution, why they declared as? does this fake advertising?

I got same results for high and mid values. There is no change. For other microcontroller brands we used like NXP and Microchip, we could always find analogue reference designs and PCB drawing suggestions.

it works now. thank you very much. :thumbs_up:

ADC resolution can not reach to 16bits. ıs there any analogue reference design?

I can not use backup RAM for STM32H743BI. Is there any application note or source code for backup RAM.
