Mr.Kang system engineer in South Korea.

Looking an ADC high performance STM32.

The specification is as follows:

1~5Msps , 2channel, PGA (if possible)

I would suggest ST's MCU finder application : https://www.st.com/en/development-tools/st-mcu-finder.html

Or, you manually browse through the online MCU data.

I'd say, almost all M4 STM32 devices make at least 1Msps. To achieve the upper 5Msps, some devices would require a dual/triple mode, where two or three ADCs units are working in an interleaved fashion.

The package type should be listed in the MCU Finder, too.

A 12 bit resolution and 8 or more channels per ADC are standard for ST's SAR-ADCs.

Does any ST MCU work in triple interleaved mode?

I ran my nucleo board stm32f429ZIT 3 with 3 adc at 3 x 2.4 = 7.2 Mhz

I run my nucleo board with stm32f303RET with 4 adc at 4 channels of 6 mHz each, or interleaved for 2 of 12 Mhz channels

This is at 10 bits, at 12 bit its only 5.14 or 10.28 mhz

The 303 also has 4 pga opamps

The F407 (at the F4 Discovery) and F74x (at the F746 Nucleo) do.

I didn't check for others.
