Hello Katherine,

The unused analog input pins of ADS1278 can be left floating, or no connection. Also, suggest connecting the /PWDNx pins of the unused channels to 0V to reduce total power consumption of the ADC.

Hi，Keith

Thank you for your reply.

Left floating, or no connection seems to be the same. Because this information is very important to my customers, I want to reconfirm it that you want to express is only the way of no connection, right？

Regards,

Katherine
