     High-Accuracy, Dual-Axis Digital Inclinometer and Accelerometer ADIS16209
The ADIS16209 programmable, dual-mode inclinometer sensor is suited to a diverse set of industrial applications that require inclination changes to be measured, including surveying equipment, factory machine tools, satellite antenna stabilization systems, motion safety monitors and automotive wheel alignment. Functionally equivalent inclinometer solutions are typically 100 times larger than the ADIS16209.

       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
Programmable alarm conditions Configurable operating parameters include
Sample rate
Power management
Digital filtering
Auxiliary analog and digital output
Offset/null adjustment
Self-test, for sensor’s mechanical structure
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 RoHScompliant solder reflow processes.

      ADIS1620x/PCB评估板
The ADIS1620x/PCBs are simple evaluation boards that provide convenient access to theADIS1620x family of products, using a standard 2 mm, 2 × 6, connector interface. Theseconnectors can be accessed using a variety of cable options, including standard 1 mm ribbon cables. The ADIS1620x/PCB is designed to be evaluated in an existing digital platform (such as MCU, DSP, FPGA, PLD) or as part of the ADISEVAL system.

      Four mounting holes (sized for 2-56 or 2 mm screws) have been provided to secure the board during evaluation.
