Highest performance dual-axis accelerometer for low-g sensing applications

Continuing its market leadership in accelerometers, Analog Devices' ADXL203 iMEMS accelerometer is the first product in a new family of high-accuracy low-g sensors. By providing more than eight times the temperature stability of the closest competitor, says the company, along with dual-axis sensing and integrated signal conditioning electronics all on a single IC, the ADXL203 addresses a wide range of low-g sensing applications where performance, board space, quality and reliability are critical. This achievement was made possible using Analog Devices' industry-leading iMEMS (integrated Micro Electro Mechanical System) surface micromachining process.
The ADXL203 and the ADXL103 single axis version, along with future product offerings in this family, are well suited for a wide range of applications. Some include: automotive stability control systems; active suspension systems that adapt to changing road conditions or driver's performance demands; precision navigation systems that supplement GPS navigation with dead-reckoning and compass tilt correction; stability compensation for industrial equipment; security alarms and motion detectors; navigation and targeting for aerospace/military systems; keystone effect correction for data/video projectors.
These ADXL accelerometers are low power, complete dual and single axis accelerometers with signal conditioned voltage outputs, all on a single monolithic IC. They operate with sensitivity stability temperature performance of ±0,3% typical over a temperature range of -40 to +125°C. Innovative design techniques were used to ensure tight sensitivity accuracy (±6% typical) and stability (typically better than 50 PPM/°C), as well as high zero-g bias accuracy (±25 mg typical) and stability (typically better than 0,1 mg/°C).
The ADXL203/103 have a range of ±1,7 g (typical), and can measure both static and dynamic acceleration (ie inclination and vibration). The outputs are analog voltages proportional to acceleration with a nominal scale factor of 1 V/g. The typical noise floor is 150 µg/rt-Hz, allowing signals below 1 mg (0,06° of inclination) to be resolved in tilt sensing applications using narrow bandwidths (<10 Hz). Bandwidths of 1 Hz to 2 kHz may be selected to suit the application.
