Digital Accelerometer

Manufacturer's Description

The ADXL180 iMEMS® accelerometer is a configurable, single axis, integrated satellite sensor that enables low cost solutions for front and side impact airbag applications. Acceleration data is sent to the control module via a digital 2-wire current loop interface bus. The communication protocol is programmable for compatibility with various automotive interface bus standards.

The sensor g range is configurable to provide full-scale ranges from ±50 g to ±500 g. The sensor signal third-order, low-pass Bessel filter bandwidth is configurable at 100 Hz, 200 Hz, 400 Hz, and 800 Hz.

The 10-bit analog-to-digital converter (ADC) allows either 8-bit or 10-bit acceleration data to be transmitted to the control module. Each part has a unique electronic serial number. The device is rated for operation from −40°C to +125°C and is available in a 5 mm × 5 mm LFCSP package.
