SCR1100-D04 SINGLE AXIS GYROSCOPE WITH DIGITAL SPI INTERFACE
Features
General Description
SCR1100-D04 is a single axis high performance gyroscope. It is part of VTI's high performance gyro family and it has the
same gyro section as the combined gyro acceleration product SCC1300-D02. The sensor is based on VTI's proven
capacitive 3D-MEMS technology and it has highly sophisticated signal conditioning ASIC with digital SPI interface. Small
robust packaging guarantees reliable operation over product lifetime. The housing is suitable for SMD mounting and the
component is compatible with RoHS and ELV directives.
SCR1100-D04 is designed, manufactured and tested against high stability, reliability and quality requirements. The
angular rate sensor provides highly stable output over wide ranges of temperature and mechanical noise. The bias
stability is in the elite of MEMS gyros and the component has several advanced self diagnostics features.
±300 º/s angular rate measurement range
Angular rate measurement around X axis
Angular rate sensor exceptionally insensitive to
mechanical vibrations and shocks
Superior bias instability for MEMS gyroscopes
(<1º/h)
Digital SPI interfacing
Enhanced self diagnostics features
Small size 8.5 x 18.7 x 4.5 mm (w x l x h)
RoHS compliant robust packaging suitable for
lead free soldering process and SMD mounting
Proven capacitive 3D-MEMS technology
Temperature range -40 °C...+125 °C
Applications
SCR1100-D04 is targeted to applications with high
stability and tough environmental requirements. Typical
applications are:
Inertial Measurement Units (IMUs) for highly
demanding environments
Platform stabilization and control
Motion analysis and control
Roll over detection
Robotic control systems
Guidance systems
Navigation systems
