1.4.4

Analog to digital conversion

Analog voltage information is amplified and filtered and converted into digital information for signal

processing inside the ASIC.

1.4.5

Signal conditioning and filtering

The block filters and conditions the measurement information needed for the application

1.4.6

Temperature measurement

The accelerometers contain a temperature sensor for temperature compensation purposes and for

use in the application.

1.4.7

Memory

Factory programmed calibration values are stored in a non-volatile memory

1.4.8

SPI

SPI interface is a simple four wire interface for communication between the component and the

application micro controller.

1.4.9

Self diagnostics

The VTI Automotive Digital Platform contains several enhanced diagnostics features to allow timely

and robust failure detection.

1.4.10 Power supply interface

The products are equipped with separate power and ground pins for analog and digital functionality

to allow high accuracy measurement.

1.4.11 Factory calibration

VTI Automotive Digital Platform accelerometers are factory calibrated. No separate calibration is

required in the application. Trimmed parameters during production include sensitivity, offset and

frequency response. Calibration parameters are stored during the manufacturing of the part inside

a non-volatile memory. The parameters are read automatically from the internal non-volatile

memory during the startup of the sensor after power on.
