Hi all,
In the datasheet it is stated that RECAL_EN is pulled to VCC with 200 kohm internally. We would like to use this feature in our application (radiation is a concern for us) so what is the recommended connection for RECAL (Pin 45)? Left open or Vcc with any resistor?
Regards,
Mehmet
Hi Mehmet,
As suggested in datasheet here. We can keep it floating.

Hi Mehmet,
RECAL_EN is a hardware function pin with weak internal pull up.
For SPI mode, you have full control of when to re-calibrate the device via SPI interface, so if you leave this pin floating (=enabled), you have both hardware and software recalibration capability. If you pull this pin to ground (=disabled), the device will not automatically recalibrate when losie lock, you have to manually recalibrate it via SPI.
