Data Sheet

FEATURES

GENERAL DESCRIPTION

Wide sensor range: 50 g to 500 g

Adjustable filter bandwidth: 100 Hz to 800 Hz

Configurable communication protocol

2-wire, current mode bus interface

Selectable sensor data resolution: 8 bit or 10 bit

Continuous auto-zero

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.

Fully differential sensor and interface circuitry

High resistance to EMI/RFI

Sensor self-test

The sensor g range is configurable to provide full-scale ranges

from ±±0 g to ±±00 g. The sensor signal third-order, low-pass

Bessel filter bandwidth is configurable at 100 Hz, 200 Hz,

400 Hz, and 800 Hz.

5.0 V to 14.5 V operation

8 bits of user-defined OTP memory

32-bit electronic serial number

Dual device per bus option

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 +12±°C and is available in a

± mm × ± mm LFCSP package.
