The ADXRS910WBRGZ-RL is a high performance in-plane gyroscope, designed for automotive rollover detection applications. The ADXRS910WBRGZ-RL also has an internal temperature sensor that is used to compensate offset and sensitivity performance, providing excellent stability over the -40°C to +105°C temperature range.
The gyroscope provides a full-scale range of ±300°/sec with a sensitivity of 80 LSB/°/sec. Its resonating disk sensor structure enables angular rate measurement around an in-plane axis. The -3 dB filter corner frequency can be selected to be 24.6 Hz, 49 Hz, 102 Hz, or 201 Hz. The sensor data output from the device is a 16-bit, twos complement word contained in a 32-bit SPI transaction. SPI communications are compatible up to 10 MHz.
The ADXRS910WBRGZ-RL is available in a 16-lead inverted SOIC package. The ADXRS910WBRGZ-RL is specified to operate at 3.3 V and 5 V, with less than 20 mA of current consumption. Its specifications are valid over the -40°C to +105°C temperature range.
