ST1VAFE3BX 50/60Hz notch filter?

[bwilkins]

In application note TN1571 "Reference design based on the ST1VAFE6AX and ST1VAFE3BX biosensors..." Table 2 mentions that ST1VAFE3BX has a selectable 50/60Hz notch filter. However, there's no further reference to this filter or how to enable it in the datasheet.

Is this an error in TN1571, or something I'm missing.

Thank you.

Hi @bwilkins ,

Yes, there is a typo. The embedded notch filter is available only in ST1VAFE6AX. For ST1VAFE3BX, if you need it, you can implement digital filtering in post process.

Thank you for confirming.
