Analog Devices has launched the ADXL206, a high precision, dual-axis, low power iMEMS accelerometer.
The accelerometer is capable of generating signal conditioned voltage outputs. The acceleration is measured at full scale with +/- 5g. The accelerometer is capable of measuring dynamic acceleration like tilt and static acceleration like gravity. The temperature range for operation is -40 to +175° C, hence, it is suitable for use in geological down hole tools and other applications where high temperatures are to be endured.
Wayne Meyer, the manager for marketing and applications, explained that the accelerometer has been designed with an in-built temperature compensation circuitry, therefore, quantization errors and non-monotonic behaviour are eliminated. Pam Aparo, the segment marketing manager for Instrumentaion at Analog Devices, claimed that the accelerometer is designed to provide measurements from deep under the earth surface and its size is a big advantage as it brings down the space occupied and also the power consumed. The noise floor is 110µg/√Hz, this is particularly useful in tilt measurements where the resolution of signals below 1 mg at narrow bandwidths (less than 60 Hz) is required. The ideal bandwidth range is 0.5 Hz to 2.5 kHz. The accelerometer comes in a side-brazed ceramic dual in-line package. Other features of the accelerometer are high zero g bias repeatability, high sensitivity, high accuracy and ability to survive 3500 g shocks.
