Hi all,

Please let me know about this device.
In the datasheet, " Pins internally not connected, do not float these pins. ".

Why don't float these?

Regards,
Nagai

    Hi Nahi

    ADS79xx has multiple variants with different number of input channels. Floating NC pins have possibility of introducing crosstalk on input channels while switching

    So it is suggested not to float these pins. Pulling down these pin is known to help

    Thanks
