4.2

IC interface

The complete measurement chain is composed of a low-noise capacitive amplifier which

converts the capacitive unbalancing of the MEMS sensor into an analog voltage using an

analog-to-digital converter.

The magnetic data may be accessed through an I2C/SPI interface thus making the device

particularly suitable for direct interfacing with a microcontroller.

The LIS2MDL features a data-ready signal which indicates when new sets of measured

magnetic data are available, thus simplifying data synchronization in the digital system that

uses the device.

4.3

Factory calibration

The IC interface is factory calibrated for sensitivity (So) and Zero-gauss level (TyOff).

The trim values are stored inside the device in nonvolatile memory. Anytime the device is

turned on, the trim parameters are downloaded into the registers to be used during active

operation. This allows using the device without further calibration.
