Qualified for automotive applications The ADXL700 device is a high precision, triaxial accelerometer
designed for electronic stability control and other high performance applications. A built in temperature compensation routine
ensures sensitivity stability to better than ±3% across the entire
temperature range. The ADXL700 is designed with selectable
−3 dB filter corner frequencies to satisfy a range of applications,
and the 2 kHz output data rate allows sufficient oversampling of
the acceleration information. APPLICATIONS The acceleration data output from the device is a true 16-bit
word and is contained in a 32-bit SPI transaction. The SPI …
