Analog Devices Inc. (ADI) has released the ADXL206, a high precision, low power, dual-axis iMEMS accelerometer with signal conditioned analog voltage outputs. The single-chip ADXL206 measures acceleration with a full-scale range of 5g and measures both dynamic acceleration such as tilt and static acceleration such as gravity. Offering a guaranteed operating temperature range of -40C175C and excellent overall stability, the ADXL206 is designed for geological down hole tools and other extreme high temperature industrial applications.

"As designers put together smart drilling systems that go miles and miles under the earth's surface, they are challenged to balance power and space requirements against the need for more information," said Pam Aparo, segment marketing manager for Instrumentation, Analog Devices. "The ADXL206 iMEMS accelerometer is not only an extremely compact solution, but it also lowers power consumption by an order of magnitude from over 10mA to under 0.5mA per axis."

The ADXL206 iMEMS accelerometer has a typical noise floor of 110?g/Hz, allowing signals below 1mg (0.06 of inclination) to be resolved in tilt sensing applications using narrow bandwidths (The ADXL206 is in full production now and priced at $789 each per 1,000.
