ADC3908S025: NC pins connection

Nick Jandieri

Part Number: ADC3908S025

Hello,

NC pins description is contradictory in the datasheet.

Should all these pins be connected to GND?

Thank you!

Hi Nick,

Sorry for the confusion, please connect those pins to ground.

Thank you!

Could you also confirm pins 14, 15 which are channel B in 2-channel devices. Should they be grounded or kept unconnected for ADC3908?

Hi Nick,

For those two pins, I would recommend either not connecting them or put in a provision to connect a 0.1uF cap to ground on each pin.

Regards,

Rob
