ADS1299: lead-off detection: what kind of square wave excitation?

Andrea Verdecchia

Part Number: ADS1299

Hi. I'm wondering if the square wave excitation current signal to perform the ac lead-off detection has a DC component or not (an offset, to be clear).

Hello Andrea,

Thanks for your post!

The AC lead-off detection should not have a DC offset.

This application report may be useful if you have not already seen it: www.ti.com/.../sbaa196a.pdf
