AIS25BA传感器变送器的运动传感器-加速计规格书PDF中文资料

AIS25BA属于传感器变送器的运动传感器-加速计。由意法半导体集团制造生产的AIS25BA运动传感器 - 加速计加速度计用于检测并响应运动或振动等加速度的变化。加速度计类型有 X、Y 或 Z 轴上的模拟或数字加速度计，加速度范围为 ±0.5 g 至 ±2000 g，灵敏度为 1 至 500 k (LSB/g)，输出类型有模拟电压、蓝牙、数字、DSI、IEPE、I2C、PCM、PWM、射频和 SPI。

描述 Description

The AIS25BA is an ultralow noise, low latency, wide bandwidth, 3-axis digital

accelerometer with a dedicated TDM interface designed to address automotive nonsafety

applications, in particular, wideband active noise control (ANC) and vibration

monitoring.

The AIS25BA has a user-selectable full-scale range of ±3.85/±7.7 g, a time-division

multiplexing (TDM) interface for the sensor data, and an I²C interface for device

configuration.

The AIS25BA is available in a small thin plastic land grid array package (LGA) and is

guaranteed to operate over an extended temperature range from -40 °C to +125 °C.
