Hi,I have a STM32G491 based design with three differential shunts, routed to the three Op Amps of the MCU. I would prefer to run the Op Amps in standalone mode. This would allow me to have a low pass filter (cap across negative and output) and I woul...

Hi Gael,thank you for your reply. We actually developed our own 3-shunt, 3-OpAmp, 3-ADC sampling code and it works great. We had to do some rework to ST code anyway to get oversampled measurements working, since you assume that the sampling time is l...

Thank you for your reply. That's very unfortunate. I checked as well - and yes it seems that the EVSPIN32G4 lacks the added ADC, but more capable G4 variants would benefit from 3-ADC measurement. Isn't it the only way to do external gain network, sim...

Then why not sample with 3 OpAmp, external network or PGA, with 3 ADC? This should be doable hardware -wise. It allows differential measurement as well. At least it's doable with G474 and such. Are you planning to add MCSDK support for this kind of t...

So let me get this straight, you have built a three standalone opamp feature in a dev kit, and I think we all agree that it's superior (differential measurement, and actually HW LPF as well), but you have no plans to support it? Why is that?

Is this something you are planning to support in an upcoming MCSDK release? We need this for our current project, and we are currently considering developing it ourselves unless the june/july MCSDK ships with out of the box support.
