ADS1294R: Using in Daisy-chain with ADS1298 and what to do with spare pins

Part Number: ADS1294R


Hi,

I'm looking to use the ADS1294R/8 in daisy-chain configuration and was wondering what to do with the spare pins on the 1294R. I currently have INP1N/p and INP2N/p for respiratory mode and the rest of the pins are unused. In the data sheet, it says that for all unused INP pins, to tie them to AVDD. Does this include pins INP5-8? These are not used at all on the ADS1294R.

Thanks,

James
