Analog Devices' 3-Axis MEMS Accelerometer Available Now; Sets Ultra-Low Power Consumption Benchmark
Norwood, MA(10/31/2005) - Analog Devices, Inc. (NYSE: ADI), innovating in MEMS technology for over a decade, today added a 3-axis accelerometer to its iMEMS® family of motion signal processing products. Recognized for its MEMS manufacturing technology and ability to combine MEMS sensor structures with signal conditioning circuitry, Analog Devices leveraged this expertise to reduce the power consumption of the new ADXL330 3-axis accelerometer to a mere 200 microamps at a supply voltage of 2.0 V, less than 50% the power of typical competing devices and the lowest in its class. Designed with mobile phone handsets and other handheld consumer electronics products in mind, the ADXL330 features a rugged, 3-axis sensor structure integrated with signal conditioning on the same die and housed in a small (4 mm x 4 mm x 1.45 mm) plastic surface mount package.
"Three-axis accelerometers will significantly change how people interface with handheld electronics. Mobile phone OEMs, who are leading this trend, have clearly articulated their requirement for a price point of $1 or less within a few years to achieve their vision of a 3-axis accelerometer as a standard handset component," said Bill Giudice, vice president and general manager, Micromachined Products Division, Analog Devices, Inc. "With the launch of the ADXL330, we are unlocking the potential of this vast market using proven 3-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 3-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.
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.
Motion-enabled gaming devices that offer a more interactive, intuitive, and fun gaming experience by improving interfaces for current games and opening new possibilities for motion-based games.
Digital still cameras that automatically help users take better pictures by sensing position, movement, and vibration.
The ADXL330 is based on iMEMS Motion Signal Processing(TM) 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 3-axis accelerometers into consumer electronics products, particularly cell phones," 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."
About the ADXL330
The ADXL330 is a small, low profile, low power, 3-axis accelerometer with signal conditioned analog voltage outputs. With a ±2 g 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 200 microamps at 2.0 V (typical). Supply voltage range is 2.0 V to 3.6 V. The ADXL330 is compatible with applications requiring bandwidths ranging from 0.5Hz to 1.6 kHz. The ADXL330 is offered in a 4 mm - 4 mm - 1.45 mm, 16-lead, plastic lead frame chip scale package, with a shock rating of 10,000 g.
Product Availability
ADXL330 samples are currently available, with volume production in Q1 2006. OEM pricing is below $2.00 for high volume consumer applications.
