High performance dual-axis accelerometer for low-g sensing

2 July 2003 Electronics Technology

Analog Devices has introduced a new accelerometer. The ADXL203 iMEMS accelerometer is the first product in a new family of high-accuracy low-g sensors. Claimed to provide more than 8 times the temperature stability of the closest competitor along with dual-axis sensing and integrated signal conditioning electronics all on a single IC, the manufacturer says that the ADXL203 addresses a wide range of low-g sensing applications where performance, board space, quality and reliability are critical.

iMEMS is Analog Devices' industry-leading 'integrated micro electro mechanical system' surface micromachining process. Says Paul Ganci, product line director, Micromachined Products Division, Analog Devices, "Our new ADXL accelerometer family was designed specifically with high-performance applications in mind. The result is a breakthrough MEMS beam design that delivers unprecedented accuracy over temperature while maintaining the low power consumption, superior linearity, proven quality and reliability our customers expect from Analog Devices' iMEMS products."

The new ADXL203 and the ADXL103 single axis version, along with future product offerings in this family, are well suited for a wide range of consumer, healthcare, automotive, industrial, and military applications. These include:

* Automotive stability control systems that help prevent skidding and maintain a driver's intended path.

* Active suspension systems.

* Precision navigation systems that supplement GPS navigation with dead-reckoning and compass tilt correction.

* Stability compensation for industrial equipment such as cranes, fork lifts, and work platforms.

* Security alarms and motion detectors.

* Aerospace and military systems for navigation and targeting.

* Keystone effect correction for data/video projectors.
