Forum Post: RE: ADS8638: getting started with EVM
Hi Alan, The MMB0 does not produce the HVDD/HVSS power - it only supports feed trough from the screw terminal at J14. You need to provide an external source for the high voltage rails.

Hi Nick, You are right, the MMB0 does not actually provide the high voltage source needed for the ADS8638EVM, you can use the screw terminals at J14 and the HVDD/HVSS sources will 'pass through' to...

Hi Olly, The modification for this circuit is simple, just leave the parallel feedback resistor disconnected (RFB2, pin10). This would make the total feedback resistance 10kohm instead of 5kohm. I...

Hi Bhagvan, Happy to help! Why do you want to keep the sampling rate fixed at 250Hz? Have you considered sampling at 500Hz and only reading every other sample?
