ADXL700WBRWZ

Accelerometer Triple ±14.2g 3.3V/5V 16Pin SOIC W Tube

Product Details

The ADXL700 device is a high precision, triaxial accelerometer designed for electronic stability control and other high perfor-mance 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.

The acceleration data output from the device is a true 16-bit word and is contained in a 32-bit SPI transaction. The SPI interface contains additional fault detection bits and data formatting bits designed to assist high reliability applications. SPI communications are compatible up to 8 MHz. The 16-bit acceleration data-word offers a resolution of 0.434 mg/LSB for the ±14.2 g full-scale range of the device.

The ADXL700 is available in an SOIC package with an inverted paddle for improved EMI/RFI robustness. The ADXL700 operates at both 3.3 V and 5 V, and is specified to operate across the full automotive temperature range of −40°C to +105°C.
