3-Axis Digital Angular Rate
Gyroscope
FXAS21002C
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.
