Features
General Description
SCA2120-D07 is a two 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. Dual Flat Lead (DFL) housing of the component guarantees robust operation over the product lifetime.
SCA2120-D07 is designed, manufactured and tested for high stability, reliability and quality requirements of
automotive applications. The accelerometer has extremely stable output over wide range of temperature, humidity and
mechanical noise. The component is qualified against AEC-Q100 standard and has several advanced self diagnostics
features. The DFL housing is suitable for SMD mounting and the component is compatible with RoHS and ELV
directives.
SCA2120-D07 is a part of VTI digital accelerometer family and fully compatible with single axis accelerometers
(SCA800 series) and other multi axis accelerometers (SCA2100 series and SCA3100 series).
