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.

Configurable operating parameters include sample rate,

power management, digital filtering, auxiliary analog and

digital output, offset/null adjustment, and self-test for sensor

mechanical structure.

The ADIS16209 is available in a 9.2 mm × 9.2 mm × 3.9 mm

LGA package that operates over a temperature range of −40°C

to +125°C. It can be attached using standard RoHS-compliant

solder reflow processes.
