The standard supply voltage (3.3 V) and serial peripheral interface (SPI) enable simple integration into most industrial system designs. A simple internal register structure handles all output data and configuration Features . This includes access to the following output data: calibrated acceleration, accurate incline angles, power supply, internal temperature, auxiliary analog and digital input signals, diagnostic error flags, and programmable alarm conditions.
