Precision Triaxial Inclinometer and Accelerometer with SPI Data Sheet ADIS16210 FEATURES GENERAL DESCRIPTION Triaxial, digital inclinometer system
The ADIS16210 iSensor® is a digital inclinometer system that
±180° measurement range, roll and pitch axes
provides precise measurements for both pitch and roll angles
±90° gravity axis
over a full orientation range of ±180°. It combines a MEMS tri-
±0.1° relative accuracy
axial acceleration sensor with signal processing, addressable user
Triaxial, digital accelerometer, high accuracy
registers for data collection/programming, and a SPI-compatible
±1.7 g measurement range
serial interface. In addition, the production process includes unit
±0.05° axis-to-axis alignment
specific calibration for optimal accuracy performance. It also
Digital internal temperature measurements
offers digital temperature sensor and power supply measurements
Digital internal power supply measurements
together with configuration controls for in-system calibration,
Programmable user calibration options
sample rate, filtering, alarms, I/O configuration, and power
Single command, frame alignment
management.
Manual accelerometer bias correction
The MEMS sensor elements are bound to an aluminum core for
Programmable operation and control
tight platform coupling and excellent mechanical stability. An
Sample rate/filtering
internal clock drives the data sampling system, which eliminates
Alarm conditions and indicator output
the need for an external clock source. The SPI and data buffer
Input/output: data ready, alarm, general-purpose
structure provide convenient access to accurate sensor data and
Power management functions
configuration controls.
SPI-compatible serial interface Serial number and device ID
The ADIS16210 is available in a 15 mm × 24 mm × 15 mm
Single-supply operation: 3.0 V to 3.6 V
module that provides mounting tabs with M2-sized mounting
Calibrated temperature range: −40°C to +85°C
holes and a flexible, edge terminated connector interface. It has
15 mm × 24 mm × 15 mm package with flexible connector
an extended operating temperature range of −40°C to +125°C.
