Technical Characteristics
Introduction to MEMS Accelerometers
The XDA205 is an industrial-grade dual-axis MEMS accelerometer featuring digital output and selectable measurement ranges of ±2g/±3g. Boasting low noise, low temperature drift and excellent long-term stability, it is ideally suited for a wide range of high-precision measurement systems. Encapsulated in a ceramic package, the XDA205 delivers reliable long-term stability in operation.
Advanced Technology
LKF-XDA205 is a high-precision, low-volume capacitive MEMS accelerometer designed for inertial applications. The device comprises a MEMS sensing element and an ASIC chip. The MEMS sensing element’s output capacitance varies with external acceleration, while the ASIC chip continuously detects this capacitance and converts it into a digital output signal. The product is independently designed, and all manufacturing processes—including packaging and testing—are localized..
High quality and reliability
LIOCREBIF ensures product quality and reduces system cost through full control over upstream and downstream processes and technologies. The company implements ISO9001 and GJB quality management systems and follows strict production processes to guarantee the reliability and consistency of product performance.
The embedded MEMS accelerometer in an inertial navigation system measures the object’s acceleration and, through associated electronic circuitry, converts it into position, orientation, and velocity information, enabling accurate navigation of moving objects.
