GENERAL DESCRIPTION
The ADIS16209 is a high-accuracy, digital inclinometer that accommodates both single axis (±180°) and dual-axis (±90°) operation. The standard supply voltage (3.3 V) and serial peripheral interface (SPI) serial interface 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.
