Part Details:

Configurable, High g, i MEMS Accelerometer ADXL180 FEATURES GENERAL DESCRIPTION Wide sensor range: 50 g to 500 g The ADXL180 iMEMS® accelerometer is a configurable, single Adjustable filter bandwidth: 100 Hz to 800 Hz axis, integrated satellite sensor that enables low cost solutions Configurable communication protocol for front and side impact airbag applications. Acceleration data 2-wire, current mode bus interface is sent to the control module via a digital 2-wire current loop Selectable sensor data resolution: 8 bit or 10 bit interface bus. The communication protocol is programmable for Continuous auto-zero compatibility with various automotive interface bus standards. Fully differential sensor and interface circuitry The sensor g range is configurable to provide full-scale ranges High resistance to EMI/RFI from ±50 g to ±500 g. The sensor signal third-order, low-pass Sensor self-test Bessel filter bandwidth is configurable at 100 Hz, 200 Hz, 5.0 V to 14.5 V operation 400 Hz, and 800 Hz. 8 bits of user-defined OTP memory 32-bit electronic serial number The 10-bit analog-to-digital converter (ADC) allows either 8-bit Dual device per bus option or 10-bit acceleration data to be transmitted to the control module. Each part has a unique electronic serial number. The device is APPLICATIONS rated for operation from -40°C to +125°C and is available in a Crash sensing 5 mm × 5 mm LFCSP package.
