Introduction
ADXRS453BRGZ - MEMS Angular Rate Sensor
The ADXRS453BRGZ is a high-performance, digital-output single-axis gyroscope (MEMS angular rate sensor) manufactured by Analog Devices Inc. (ADI). Designed to precisely measure angular rate (rotational speed) around the Z-axis (yaw axis), it provides accurate rotational speed data in digital format via an SPI interface, even in environments with high levels of vibration and shock.
Key Specifications
| Feature | Specification | Details / Significance |
|---|---|---|
| Device Type | Z-Axis (Yaw) MEMS Gyroscope | Measures rotational speed around the vertical axis. |
| Sensing Range | ±300°/s | Can measure rotation rates up to 300 degrees per second in both directions. |
