Rol over Detection In-Plane Gyroscope Data Sheet ADXRS910 FEATURES GENERAL DESCRIPTION High performance, in-plane roll rate gyroscope
The ADXRS910 is a high performance in-plane gyroscope,
Temperature compensated, high precision offset and
designed for automotive rollover detection applications. The
sensitivity performance
ADXRS910 also has an internal temperature sensor that is used
2°/sec rms maximum gyroscope noise
to compensate offset and sensitivity performance, providing
Serial port interface (SPI) digital output with 16-bit data
excellent stability over the −40°C to +105°C temperature range.

The gyroscope provides a full-scale range of ±300°/sec with a
<20 mA quiescent current consumption
sensitivity of 80 LSB/°/sec. Its resonating disk sensor structure
3.3 V and 5 V operation
enables angular rate measurement around an in-plane axis. The
