ADI Unveils First Accelerometer With MIN/MAX Offset Sensitivity
Analog Devices, Inc. (ADI) has introduced what it says is the industry's first MEMS accelerometer with Min/Max offset sensitivity over the full temperature range.
The 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. These capabilities make it easier to provide predictable and quantifiable performance across the full temperature range of −40°C to +85°C.
MEMS accelerometers on the market today specify only typical offset sensitivity to temperature, requiring calibration over temperature to maintain accurate sensor readings.
The ADXL350 Min/Max offset sensitivity to temperature specifications are said to guarantee quantifiable offset sensor measurements. Even in applications that are subjected to a wide temperature range.
Also, the ADXL350 offers low noise density enabling designers to obtain valid measurements from applications with a low noise floor.
The device also offers on-board analogue to digital conversion with 13-bit resolution, as low as 2 mg/LSB, and is configurable to ± 1g/2g/4g/8g range settings. The ADXL350 is available in a footprint of 3 mm x 4 mm x 1.2 mm, and comes in a 16-lead, plastic-cavity laminate package.
The device is suited for high-performance applications in the industrial and defence industries. These include gas and water meters, environmental monitors and military communications radios.
The device has a 2 mg/LSB resolution with a 13-bit on-chip A/D converter enables measurement of inclination changes less than 1°C.
Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation.
The ADXL350 is available now and the price each per 1,000 is $4.57.
