产品概述
描述
The AIS25BA is an ultralow noise, low latency, wide bandwidth, 3-axis digital accelerometer with a dedicated TDM interface designed to address automotive non-safety 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.
