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

The ADIS16209 is available in a 9.2 mm × 9.2 mm × 3.9mm
LGA package that operates over a temperature range of −40°C
to +125°C. It is capable of being attached using standard RoHS-
compliant solder reflow processes.
