Dear TI experts,
According to the datasheet, the buffered signal of INxA acts as the drive signal for the active shield.
But the oscilloscope shows a 180° phase difference between the signals on INxB and INxA.
For differential sensor configuration, do I need to configure the active shield as shown below?
where INxA and INxB each have their own active shield.
And is there a crosstalk issue with this configuration?
Or the buffered signal of INxA is sufficient for the sensor in differential configuration.
Best regards,
Will
