3.5

Factory calibration

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

The trimming values are stored inside the device in a non volatile memory. Any time the

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

during the active operation. This allows to use the device without further calibration.

3.6

FIFO

The LIS3DH contains a 10 bit, 32-level FIFO. Buffered output allows 4 operation modes:

FIFO, stream, trigger and FIFO ByPass. Where FIFO bypass mode is activated FIFO is not

operating and remains empty. In FIFO mode, data from acceleration detection on x, y, and z-

axes measurements are stored in FIFO.

3.7

Auxiliary ADC

The LIS3DH contains an auxiliary 10 bit ADC with 3 separate dedicated inputs.
