FXAS21002CQR1

3-Axis Digital Angular Rate Gyroscope

FXAS21002C is a small, low-power, yaw, pitch, and roll angular rate gyroscope with 16 bit ADC resolution. The full-scale range is adjustable from ±250°/s to ±2000°/s. It features both I2C and SPI interfaces.

FXAS21002C is capable of measuring angular rates up to ±2000°/s, with output data rates (ODR) from 12.5 to 800 Hz. An integrated Low-Pass Filter (LPF) allows the host application to limit the digital signal bandwidth. The device may be configured to generate an interrupt when a user-programmable angular rate threshold is crossed on any one of the enabled axes.
FXAS21002C is available in a plastic, 24-lead QFN package; the device is guaranteed to operate over the extended temperature range of –40 °C to +85 °C.
