Would you please help with question about ADS1298 external PACE Detection reference design TIPD111 from my customer Times? thanks.
1. Is there any any modification needed on the circuit if customer want to change to 3.3V supply? or is there anything need to pay attention to?
2. what is the function of PACE_RESET button? if customer don't want use a button, can they use a I/O to control it or just tie to GND or VCC?
3. ADS1298 have two PACE_OUTPUT for EVEN and ODD channels, customer should just tie these two pins together and connect to PACE detection ckt input?
