The ADIS16209 is a high accuracy, digital inclinometer that Configurable operating parameters include sample rate, accommodates both single-axis (±180°) and dual-axis (±90°) power management, digital filtering, auxiliary analog and operation. The standard supply voltage (3.3 V) and serial digital output, offset/null adjustment, and self-test for sensor peripheral interface (SPI) enable simple integration into most mechanical structure. industrial system designs. A simple internal register structure The ADIS16209 is available in a 9.2 mm × 9.2 mm × 3.9 mm handles all output data and configuration features. This LGA package that operates over a temperature range of −40°C includes access to the fol owing output data: calibrated to +125°C. It can be attached using standard RoHS-compliant acceleration, accurate incline angles, power supply, internal solder reflow processes. temperature, auxiliary analog and digital input signals, diagnostic error flags, and programmable alarm conditions.
