It is a complete sensing system with on-chip mixed signal processing. The MXA6500E measures acceleration with a full-scale range of ±0.5 g and a sensitivity of 500mV/g @3V at 25°C. It can measure both dynamic acceleration (e.g. vibration) and static acceleration (e.g. gravity). The MXA6500E design is based o...
