GENERAL DESCRIPTION
The ADIS16209 is a high-accuracy, digital inclinometer, that
accommodates both single axis (±180°) and dual-axis (±30°)
operation. The standard supply voltage (+3.3 V) and 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
