Hello,
I have a question about the BOOSTXL-DRV8301 as reference to build my own hardware.
What is the best position for the 1000pF capacitor over the differential measurement signal from the shunt. I see on the BOOSTXL-DRV8301 (C31,C32 and C33) layout that they are placed as close as possible to the shunt. On the other hand on the DRV8301-69M-KIT they (C75,C78 and C84) are placed as close as possible to the Op Amp and resistors.
And second question:
The 1.65V reference voltage for the third shunt measurement Op Amp is generated by an OPA374 Op Amp in voltage follower mode. Is it correct to place a 2.2uF (C38) capacitor on the output of this Op Amp, because in the datasheet I read that it can drive only 250pF in unity gain.
Thanks
