ADXRS453BRGZ - MEMS Angular Rate Sensor by Analog Devices Inc.

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.
Output Type	Digital (SPI)	16-bit data word within a 32-bit SPI message. Provides noise resistance and easy interface with microcontrollers.
Supply Voltage	3.15 V to 5.25 V	Wide operating range compatible with both 3.3V and 5V systems.
Supply Current	6 mA (typical)	Relatively low power consumption for its performance level.
Bandwidth	77.5 Hz	Determines the frequency range of the signals it can accurately measure.
Sensitivity	80 LSB/°/s	Least Significant Bits per degree per second. Scales the digital output to the physical rate.
Vibration Rejection	0.01°/sec/g (typical)	Key feature: Exceptional immunity to linear acceleration and vibration.
Bias Stability	16°/hour	Excellent long-term stability of the zero-rate output.
Operating Temperature	-40°C to +105°C	Wide temperature range suitable for industrial and automotive applications.
Shock Survival	2000 g	High robustness against mechanical shock.
Package	16-lead SOIC_CAV	Plastic cavity SOIC package for Z-axis response.

Typical Applications

Industrial Automation & Instrumentation: Rotation sensing in machinery, vibration monitoring for predictive maintenance, and motion control in robotic arms.
Aerospace and Defense: Inertial navigation systems (INS) for UAVs, satellites, and aircraft attitude control.
Automotive Safety Systems: Electronic Stability Control (ESC) and rollover detection/prevention systems.
Platform Stabilization: Drones, camera gimbals, and antenna positioning systems.
High-Vibration Environments: Internal combustion engines and heavy machinery.
