ADXL357BEZ

加速度计, MEMS, 数字, X, Y, Z, ± 10.24g, ± 20.48g, ± 40.96g, 2.25 V, 3.6 V, LCC

Product Details

The analog output ADXL356 and the digital output ADXL357 are low noise density, low 0 _g_ offset drift, low power, 3-axis accelerometers with selectable measurement ranges. The ADXL356B supports the ±10 _g_ and ±20 _g_ ranges, the ADXL356C supports the ±10 _g_ and ±40 g ranges, and the ADXL357 supports the ±10.24 g, ±20.48 g, and ±40.96 g ranges.

The ADXL356/ADXL357 offer industry leading noise, minimal offset drift over temperature, and long-term stability, enabling precision applications with minimal calibration.

Low drift, low noise, and low power ADXL357 enables accurate tilt measurement in an environment with high vibration, such as airborne IMUs. The low noise of the ADXL356 over higher frequencies is ideal for wireless condition monitoring.

The ADXL357 multifunction pin names may be referenced by their relevant function only for either the SPI or I2C interface.
