Factory calibration
The IC interface is factory calibrated for sensitivity and zero level. The trimming values are
stored in the device in non volatile memory. Any time the device is turned on, the trimming
parameters are downloaded to the registers to be used during normal operation. This allows
use of the device without further calibration.
