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 tri-
axial 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, I/O configuration, and power
management.
The MEMS sensor elements are bound to an aluminum core for
tight platform coupling and excellent mechanical stability. An
internal clock drives the data sampling system, which eliminates
the need for an external clock source. The SPI and data buffer
structure provide convenient access to accurate sensor data and
configuration controls.
The ADIS16210 is available in a 15 mm × 24 mm × 15 mm module
that provides mounting tabs with M2-sized mounting holes and a
flexible, edge terminated connector interface. It has an extended
operating temperature range of −40°C to +125°C.
