ADS1298: Unused WCT

user6529224

Part Number: ADS1298

Dear TI team,

I am using two ADS1298/R for an ECG application.

I will use the WCT from one module to drive the negative inputs of the unipolar channels of the second module.

As a result, I won't be using the WCT Amplifier from the second module:

Shall I leave the pin WCT of the second module open ?

Thank you,

Hi Paul-Alexandre,

Thanks for the post.

The WCT can be left floating (NC - no connect) is unused. You can also power down the unused WCT amplifiers internally to save power.

Thanks,

-TC
