Product Description

MEMS Gyroscope Chip for Inertial Measurement Unit

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 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 for voltage stability
Avoid routing under the package for smooth assembly
Position components away from stress concentration areas, heat sources, and mechanical contact points

Installation Guidelines

High-performance MEMS gyroscope is a high-precision test equipment. To achieve optimal design performance, consider these installation recommendations:

Evaluate sensor placement using thermal analysis, mechanical stress simulation (bending measurement/FEA), and impact robustness testing
Maintain appropriate distance from:
- PCB thickness recommendations: 1.6-2.0mm to minimize inherent stress
- Buttons/mechanical stress points
- Heat sources (controllers, graphics chips) that may raise PCB temperature
Avoid placement in areas prone to mechanical stress, warping, or thermal expansion
