ADIS16470/PCBZ Breakout Board Features  

The ADIS16470/PCBZ Breakout Board provides direct access to the capabilities of the ADIS16470 MEMS IMU. This high-precision inertial measurement unit offers a comprehensive suite of features for accurate motion tracking and analysis. Let’s explore its notable features:

High-Precision Triaxial Sensing

The ADIS16470/PCBZ Breakout Board delivers precise inertial measurements through its integrated triaxial gyroscope and accelerometer. The gyroscope features a ±2000°/sec dynamic range and an impressive 8°/hr in-run bias stability, enabling accurate angular rate sensing. Complementing this, the triaxial accelerometer provides a ±40 g dynamic range with a 13 μg in-run bias stability for precise linear acceleration measurements. Both sensors output delta angle and delta velocity data, suitable for applications demanding detailed motion analysis. 

Factory Calibration and Compensation

To ensure optimal performance, each sensor undergoes rigorous factory calibration for sensitivity, bias, and axial alignment. This calibration process, conducted across a temperature range of -10°C to +75°C, guarantees accurate measurements in varying conditions. Furthermore, the sensors incorporate dynamic compensation formulas to mitigate environmental influences, minimizing the need for additional system-level calibration.

Data Communication and Control

The ADIS16470 supports SPI-compatible data communications, offering a reliable interface for data collection and configuration. Users can fine-tune sensor performance through programmable operation and control features, including automatic and manual bias correction. The breakout board also includes a data-ready indicator for synchronous data acquisition, and external sync modes that offer direct, pulse, scaled, and output synchronization options.

Durability and Operational Range

Engineered for durability, the ADIS16470/PCBZ can withstand mechanical shocks up to 2000 g, making it suitable for harsh industrial applications. With a wide operating temperature range of -25°C to +85°C and a single supply voltage requirement (3.0 V to 3.6 V), this module ensures reliable operation in challenging conditions. On-demand self-tests for both inertial sensors and flash memory enhance system reliability and provide valuable diagnostic information.

The ADIS16470 IMU is housed in a compact 44-ball BGA package measuring approximately 11 mm x 15 mm x 11 mm. This small footprint enables integration into space-constrained designs.
