Which MCU in STM32 family is the best selection for using SAR 16-bit ADC related project

[RongShengWang]

Questions:

1. How many STM32 families offer SAR 16-bit ADCs?

2. Which MCU in STM32 family is the best choice for using SAR 16-bit ADC related project with the lowest cost?

Thanks

Hello @RongShengWang 

I suggest you use one of the STM32H7 MCUs mentioned in this table:

More details can be found on the AN5354.

Hi,

   Thanks - I did read the docs you sent.

    I still have the question - Why STM32H7 is better than STM32F3's SAR 16-bit ADC - Our focus is only on SAR 16-bit ADC and the cost -

   since - 

        (1). We use two SAR 16-bit ADC with very low sampling rate - 10KS/s.

        (2). We only use 1 external analog input on each SAR 16-bit ADC.

        (3). The accuracy and the cost are to be compared.

    I wish to know more details.

    Thanks,

Rong

in fact, the STM32F3 will be the best choice but as you can see on the ARM®Cortex®-M4 32b MCU+FPU, up to 256KB Flash+32KB SRAM, timers, 4 ADCs (16-bit Sig. Delta / 12bit SAR), 3 DACs, 2 comp., 2.0-3.6 V the STM32F3 include 12-bit SAR and 16-bit Sig Delta ADC:

But, what you were asking for is SAR 16-bit ADCs that is available on the STm32H7 that I've mentioned you. 

Best Regards.

Thanks,

You said "in fact, the STM32F3 will be the best choice".。

Why -

1. Because the accuracy of SAR 16-bit ADC in STM32F3 is better than STMH7? 

2. Because of its lower price?

Could you specify the part number in STM32F3 for me? Thanks,

Rong
