"With the launch of the ADXL330, we are unlocking the potential of this vast market using proven three-axis core technology and a product roadmap that will drive future price points of $1 or less in high volumes, while providing the capability designers need today to transform the way consumers use mobile phones, media players, video games, cameras, and computers".
As the first product in a family of Analog Devices three-axis accelerometers, the ADXL330 is ideally suited for a wide range of consumer product applications requiring low power, small packaging, and reliable 3-axis sensing.
Examples include mobile phones with motion-sensing and situational-awareness to monitor where the handset is and how it is being used.
This enables features such as more intuitive user interfaces and smart power management to extend battery life.
In notebook computers and media players with disk drive protection systems, measuring shock and drop events facilitates increased robustness, as the demand for storage capacity in portable devices increases.

The ADXL330 is based on iMEMS Motion Signal Processing technology with a proven quality, reliability, and on-time delivery record backed by more than 200 million sensors shipped.
This experience enables Analog Devices to successfully serve high volume consumer markets.
"Low power consumption and small package size are absolutely critical to the integration of three-axis accelerometers into consumer electronics products, particularly cellphones", said MEMS analyst Marlene Bourne, Senior Director of Nanotechnology and MEMS - Research, Global Crown Capital.
"The ability to meet those needs, and in high volumes, is expected to result in the rapid adoption of motion sensing for countless consumer applications".
The ADXL330 is a small, low profile, low power, three-axis accelerometer with signal conditioned analogue voltage outputs.
With a +/-2g range, it is capable of measuring the static acceleration of gravity for tilt-sensing applications, as well as dynamic acceleration resulting from motion, shock, or vibration.
Power consumption is extremely low, less than 200uA at 2.0V (typical).
Supply voltage range is 2.0 to 3.6V.
The ADXL330 is compatible with applications requiring bandwidths ranging from 0.5 to 1.6 kHz.
The ADXL330 is offered in a 4 x 4 x 1.45mm, 16-lead, plastic lead frame chip scale package, with a shock rating of 10,000 g.
ADXL330 samples are currently available, with volume production in Q1 2006.
