High Stability Inertial Sensor MEMS Gyro Chip for OEM IMU Integration

High Stability Inertial Sensor MEMS Gyro Chip for OEM IMU Integration

Our MEMS gyroscope chip delivers high-precision angular rate sensing for advanced inertial navigation and motion control applications. Designed with aerospace-level reliability and industrial-grade durability, it provides ultra-low noise, low bias instability, and excellent temperature stability for platforms that require long-term accuracy and robust performance.

Engineered for UAVs, autonomous robots, and industrial equipment, this MEMS gyro chip offers fast dynamic response, compact form factor, and low power consumption — making it ideal for embedded navigation systems and precision motion platforms.

PCB Design Guidelines
  • Decoupling capacitors for pins VCP, VREF, VBUF, and VREG should be placed as close to the pins as possible, with minimized trace equivalent resistance
  • Other ends of decoupling capacitors for VREF, VBUF, and VREG should connect to nearest AVSS_LN and then to signal ground via a magnetic bead
  • Decoupling capacitors for VCC and VIO must be placed close to corresponding pins
  • VCC operation requires about 35mA current — use wide PCB traces to ensure voltage stability
  • Avoid routing under the package for smooth assembly
  • Position components to avoid stress concentration areas, large heat dissipation elements, mechanical contact points, and warping-prone locations

Installation Guidelines

This high-performance MEMS gyroscope is precision equipment. For optimal performance, consider these installation recommendations:

  • Evaluate sensor placement using thermal analysis, bending measurement, and finite element simulation
  • Perform drop tests after soldering to verify impact robustness
  • Maintain distance from stress concentration points:
    • Use PCB thickness of 1.6-2.0mm to minimize inherent stress
    • Avoid placement near buttons or mechanical stress points
    • Keep away from heat sources like controllers or graphics chips
