GENERAL DESCRIPTION

The ADIS16210 iSensor® is a digital inclinometer system that provides precise measurements for both pitch and roll angles over a full orientation range of ±180°. It combines a MEMS triaxial acceleration sensor with signal processing, addressable user registers for data collection/programming, and a SPI-compatible serial interface. In addition, the production process includes unit specific calibration for optimal accuracy performance. It also offers digital temperature sensor and power supply measurements together with configuration controls for in-system calibration, sample rate, filtering, alarms, input/output (I/O) configuration, and power management.
