Semiconductor manufacturer Analog Devices, Inc. has recently unveiled the industry's first MEMS accelerometer with Min/Max offset sensitivity over the full temperature range.

Analog Devices' ADXL350 3-axis MEMS accelerometer has maximum offset temperature sensitivity of 0.31 mg/C on the X/Y axes and 0.49 mg/C on the Z axis, guaranteeing predictable and quantifiable performance across the full temperature range of -40C to +85C. MEMS accelerometers on the market today specify only typical offset sensitivity to temperature, requiring calibration over temperature to maintain accurate sensor readings.

ADI's latest accelerometer offers on-board analogue to digital conversion with 13bit resolution, as low as 2 mg/LSB, and is configurable to 1g/2g/4g/8g range settings. The ADXL350 is available in a small footprint 3-mm x 4-mm x 1.2-mm, 16-lead, plastic-cavity laminate package. The ADXL350 is well suited for high-performance applications in industrial and defence industries such as gas/water meters, environmental monitors and military communications radios.

The MEMS accelerometer's Min/Max offset sensitivity to temperature specifications guarantee known, quantifiable offset sensor measurements even in applications that are subjected to a wide temperature range. Additionally, the ADXL350 offers low noise density enabling designers to obtain valid measurements from applications with a low noise floor.
