Rollover Detection In-Plane Gyroscope ADXRS910 Data Sheet FEATURES GENERAL DESCRIPTION High performance, in-plane roll rate gyroscope Temperature compensated, high precision offset and sensitivity performance 2/sec rms maximum gyroscope noise Serial port interface (SPI) digital output with 16-bit data word <20 mA quiescent current consumption 3.3 V and 5 V operation -40C to +105C temperature range 16-lead SOIC_CAV surface-mount package for in-plane roll rate sensing AEC-Q100 qualified for automotive applications The ADXRS910 is a high performance in-plane gyroscope, designed for automotive rollover detection applications. The ADXRS910 also has an internal temperature sensor that is used to compensate offset and sensitivity performance, providing excellent stability over the -40C to +105C 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 27.6 Hz, 51.3 Hz, 109 Hz, or 196.8 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. APPLICATIONS The ADXRS910 is available in a 16-lead inverted SOIC package. The ADXRS910 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 -40C to +105C temperature range.
