Bio-sensing tools

Other Parts Discussed in Thread: AFE4960

Dear in-charge person.

I have a question about Bio-sensing tools.
While evaluating the AFE4860 EVM by using the Bio-sensing tools,
I observe the -1.19V on ECG_CH1 in the open electrodes status.
But it is different to the datasheet of AFE4960 description.
it says ”The ADC full-scale input range (±FS) is nominally ±1.11 V ”.
So there's no way that I observe the -1.19V.

Why does the Bio-sensing tools display the 1.19V?

Thanks,
Takayuki Sato.
