ADXL1003 MEMS Accelerometer with Wide Bandwidth an

ADI’s ADXL1003 is a low noise, wide bandwidth, microelectronic mechanical systems (MEMS) accelerometer. It has typical noise density of 45 μg/√Hz across the linear frequency range. It has a very stable and repeatable sensitivity and is immune to external shocks up to 10,000 g. The integrated signal conditioning electronics enable such features as full electrostatic self-test (ST) and an overrange (OR) indicator, useful for embedded applications. With low power and single-supply operation of 3.0 V to 5.25 V, the accelerometer also enables wireless sensing product design. The ADXL1003 is available in a small 32-pin LFCSP package and operates over the -40°C to +125°C temperature range. The ADXL1003 is ideal for predictive maintenance, asset health, and condition-based monitoring.
