General Description

1.1

Introduction

VTI Automotive Digital Accelerometer Platform is an accelerometer product concept based on VTI

capacitive 3D-MEMS technology. The VTI ADP platform integrates high accuracy micromechanical

acceleration sensing together with a flexible SPI digital interface. The products within the platform

range from single axis accelerometers into two or three axis accelerometers. Dual Flat Lead (DFL)

housing of the component guarantees robust operation over the product lifetime.

The products are designed, manufactured and tested for high stability, reliability and quality

requirements of automotive applications. The accelerometers have extremely stable output over

wide range of temperature, humidity and mechanical noise. The components are qualified against

AEC-Q100 standard and have several advanced self diagnostics features. The DFL housing is

suitable for SMD mounting and the component is compatible with RoHS and ELV directives.

This Product Family Specification describes the VTI Automotive Digital Accelerometer Platform

common characteristics and how to operate with the products. Detail product specification is

described in individual data sheets of each product.
