Factory calibration

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 acceleration data may be accessed through an I2C/SPI interface thus making the

device particularly suitable for direct interfacing with a microcontroller.

The LIS2DS12 features a data-ready signal which indicates when a new set of measured

acceleration data is available, thus simplifying data synchronization in the digital system that

uses the device.

Factory calibration

The IC interface is factory-calibrated for sensitivity (So) and Zero-g offset.

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

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

active operation. This allows using the device without further calibration.
