  • Hi,

    May I know how you will be using AD8129? There are a lot of configurations available for this part seen on page 32 onwards. FB bin is mainly used for gain setting. And Ref pin to be used as offset or level translator. You should connect Ref to GND if not in use.

    For PD pin connect it to positive supply to enable the device.
