Analog Devices (ADI) released for general availability today the ADXL206 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 ±5 g and measures both dynamic acceleration such as tilt and static acceleration such as gravity. Offering a guaranteed operating temperature range of -40 °C to +175 °C and excellent overall stability, the ADXL206 is well suited for geological down hole tools and other extreme high temperature industrial applications.
“Instead of using additional temperature compensation circuitry, innovative design techniques have been used to ensure that high performance is built in,” said Wayne Meyer, marketing and applications manager, MEMS/Sensors Technology Group, Analog Devices. “As a result, there is essentially no quantization error or non-monotonic behavior, and temperature hysteresis is very low, typically less than 2 mg over the entire −40 °C to +175 °C temperature range. This is another example of ADI's high performance MEMS inertial sensor leadership.”
“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 10 mA to under 0.5 mA per axis.”
The ADXL206 iMEMS accelerometer has a typical noise floor of 110 μg/√Hz, allowing signals below 1 mg (0.06° of inclination) to be resolved in tilt sensing applications using narrow bandwidths (<60 Hz). Bandwidths of 0.5 Hz to 2.5 kHz can be selected to suit the application. The ADXL206 is available in a 13 mm × 8 mm × 2 mm, 8-lead, SBDIP (side-brazed ceramic dual in-line package) package.
