What are key features of IIS3DHHC 3-axis accelerometers?
IIS3DHHC 3-axis low-noise accelerometer, first accelerometer from ST with inclinometer accuracy.
With full-scale range of ±2.5g, the IIS3DHHC 3-axis accelerometer is optimized for fine-positioning mechanisms and detecting small movements such as in advanced security sensors. Among key differences between this and typical consumer-oriented accelerometers, its ultra-low noise of 45μg/√Hz (micro-g per root Hz) allows very high resolution. In addition, the IIS3DHHC integrates analog-digital conversion, as well as digital circuitry including FIFO data storage and interrupt control. This saves external conversion components and also simplifies power management to reduce energy demand and to enable longer runtimes for battery-powered equipment.
