Dual-axis, High Performance Accelerometer with Dual Spectrum Signal Processing

Product Details

The ADXL195/ADXL295 are dual spectrum accelerometers that measure baseband acceleration in up to two axes (XL-X and XL-Y), as well as high frequency (HF) acceleration energy. Identical, independent X and Y sense structures are implemented to achieve the best possible fail-safe performance.

The XL-X and XL-Y channels output baseband acceleration information with a nominal full-scale range of ±120 g and a bandwidth of 408 Hz. The acceleration data is provided as a 12-bit, twos complement word with a resolution of 62.5 mg/LSB.

HF acceleration within the frequency band of 15.5 kHz to 23 kHz is rectified and filtered to generate an average g (gAVG) energy measurement. The HF channel has a nominal full-scale range of 40 gAVG and a bandwidth of 393 Hz. When combined with the XL-X and XL-Y information, HF acceleration information allows for enhanced vehicle impact detection and discrimination.

The ADXL195/ADXL295 are available in a 16-lead, narrow-body SOIC package with an exposed pad. The ADXL195/ADXL295 can operate at 3.3 V and 5 V and are specified for operation from −40°C to +105°C.
