AIS25BA 3-Axis Accelerometer
STMicroelectronics' AIS25BA is an ultra-low noise, low latency, wide bandwidth, three-axis digital accelerometer with dedicated time-division multiplexing (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 g/±7.7 g, a 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.
