Three-axis accelerometer boasts low power consumption

Analog Devices added a three-axis accelerometer to its iMEMS family of motion signal processing products. The power consumption of the ADXL330 accelerometer is just 200 ╬ťA at a supply voltage of 2.0 V, less than 50% the power of typical competing devices. Designed with mobile phone handsets and other handheld consumer electronics products in mind, the ADXL330 features a rugged, three-axis sensor structure integrated with signal conditioning on the same die and housed in a 4- by 4- by 1.45-mm plastic surface-mount package with a shock rating of 10,000 g.

Application examples include mobile phones with motion-sensing and situational-awareness to monitor where the handset is and how it is being used; notebook computers and media players with disk drive protection systems; motion-enabled gaming devices; and digital still cameras,

The ADXL330 offers signal conditioned analog voltage outputs. With a +/-2 g-range, it's capable of measuring the static acceleration of gravity for tilt-sensing applications, as well as dynamic acceleration resulting from motion, shock, or vibration. Supply voltage range is 2.0 to 3.6 V. The ADXL330 is compatible with applications requiring bandwidths ranging from 0.5 Hz to 1.6 kHz. Samples are currently available, with volume production in Q1 2006. OEM pricing is below $2.00 for high-volume consumer applications.
