General Description
The SCA820-D03 is a single axis accelerometer component based on VTI capacitive 3D-MEMS technology. The
component integrates high accuracy micromechanical acceleration sensing together with a flexible SPI digital
interface. The component's Dual Flat Lead (DFL) housing guarantees robust operation over the product lifetime.
The SCA820-D03 is designed, manufactured and tested for high stability, reliability and quality requirements of
automotive applications. The accelerometer has extremely an stable output over wide ranges of temperature, humidity
and mechanical noise. The component is qualified according to the AEC-Q100 standard and has several advanced
self diagnostics features. The DFL housing is suitable for SMD mounting and the component is compatible with the
RoHS and ELV directives.
The SCA820-D03 is a part of VTI's digital accelerometer family and is compatible with its single axis accelerometers
(SCA8X0 Series) and other multi axis accelerometers (SCA21X0 Series and SCA3100 Series).
