ADIS16201 Rev. A is a programmable dual-axis inclinometer/accelerometer with 12-bit and 14-bit digital inclination/acceleration sensor outputs. It can measure a +1.7 g accelerometer range and a +90° inclinometer range with linear output. It also has a 12-bit digital temperature sensor output. The device features digitally controlled sensitivity and bias calibration, sample rate, and frequency response. It has dual alarm settings with rate/threshold limits, auxiliary digital I/O, digitally activated self test, digitally activated low power mode, SPI-compatible serial interface, auxiliary 12-bit ADC input and DAC output, and single-supply operation. It is suitable for platform control, stabilization, and leveling, tilt sensing, inclinometers, motion/position measurement, and monitoring applications.
The ADIS16201 is a complete dual‑axis acceleration and inclination measurement system in a compact LGA package. It provides factory‑calibrated digital sensor data via an SPI‑compatible serial interface, supporting linear acceleration, inclination angle, temperature, power‑supply monitoring, and an auxiliary analog input. Built‑in features such as configurable alarms, low‑power mode, and digital self‑test simplify system design.
The datasheet includes full specifications, pin configuration, timing diagrams, absolute maximum ratings, and typical performance characteristics. It also details power‑supply requirements, calibration registers, and recommended board layout for optimal operation.
