The ADIS16467-2BMLZ is a member of ADI’s high-performance MEMS inertial module family. Housed in a module-level package, it integrates a triaxial angular rate sensor and a triaxial accelerometer, supports SPI communication, and features synchronous inputs. The “-2” suffix on this model number indicates a gyroscope range of ±125°/s and an accelerometer range of ±8 g, making it suitable for applications requiring high accuracy in angular motion detection and dynamic response. All sensors are factory temperature calibrated to ensure high consistency across the industrial temperature range. The module is housed in a metal aluminum package measuring 22 × 22 × 9 mm and equipped with standard connectors for rapid integration into target systems.

Integration Advantages and Design Considerations
- Factory Multi-Point Temperature Calibration
Each ADIS16467 module is factory-calibrated for bias, sensitivity, and cross-axis error over a temperature range, maintaining high-precision output in an environment ranging from −40°C to +105°C, eliminating the need for manual temperature compensation on the user side.
- Programmable FIR Filter
The built-in digital filtering structure allows users to customize bandwidth and sampling rate to adapt to different system response requirements in high-speed dynamic or low-speed stable scenarios.
- Synchronous Sampling Mechanism
Supports external trigger (SYNC_IN) input to achieve hardware-level time alignment with GPS, radar, optical flow, or other sensors, facilitating high-precision timing synchronization in multi-sensor fusion systems.
- Modular Packaging Simplifies System Integration
The module adopts a metal shell and standard connector design, eliminating the need for MEMS die-level protection and conditioning circuit design, making it easy to directly integrate into industrial control boards, unmanned systems, and navigation core boards.
Typical Application Areas
Application Directions | Application Value |
Industrial Automation and Robotics | Achieve high-stability attitude control, path compensation and platform stabilization |

Drilling and geological surveying instruments | Provides continuous posture tracking and vibration feature recognition capabilities |
System Design Recommendations
- Power Supply Management:It is recommended to use a 3.3V regulated power supply with a power ripple of less than 10 mV to help reduce noise-sensing errors;
- SPI Interface Design:The wiring should be short and have matched impedance to avoid clock glitches and ensure reliable high-speed communication;
- Installation Method:The module needs to be fixed to the mainboard or structural parts with a rigid connection to avoid resonance or mechanical interference;
- ESD/EMC Protection:It is recommended to add a TVS tube and RC filter network to improve the system-level electromagnetic compatibility;
Attitude Fusion Algorithm: can be combined with AHRS, EKF or Kalman filter framework to obtain attitude angle and heading angle estimation.
The ADIS16467-2BMLZ, with its advantages in bias stability, temperature compensation, synchronous sampling, and modular packaging, provides a reliable core sensing component for industrial navigation systems, inertial-aided positioning, and multi-sensor fusion platforms. Its stability, ease of deployment, and low system integration threshold have made it widely adopted in unmanned systems, autonomous driving, surveying and exploration, and other fields.
