Programmable 360° Inclinometer
ADIS16203
FEATURES
0° to 360° Inclinometer
angle data in a convenient format that can be accessed using a
serial peripheral interface (SPI). The SPI interface provides access
to multiple measurements: 360° linear inclination angles, 1ꢀ0°
linear incline angles, temperature, power supply, and one auxiliary
analog input. Easy access to calibrated digital sensor data provides
developers with a system-ready device, reducing development
time, cost, and program risk.
180 output format option
14-bit digital inclination outputs
Linear output, 0.025° resolution
12-bit digital temperature sensor output
Digitally controlled bias calibration
Digitally controlled sample rate
Digitally controlled filtering
Unique characteristics of the end system are accommodated
easily through several built-in features, such as a single-command
offset calibration, along with convenient sample rate and band-
width control.
Digitally controlled direction/orientation
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
Single-supply operation: 3.0 V to 3.6 V
3500 g powered shock survivability
The ADIS16203 offers the following embedded features that
eliminate the need for external circuitry and provide a simplified
system interface:
•
•
•
•
•
Configurable alarm function
APPLICATIONS
Tilt sensing, inclinometers
Platform control, stabilization, and leveling
Motion/position measurement
Monitor/alarm devices (security, medical, safety)
Robotics
Auxiliary 12-bit analog-to-digital converter (ADC)
Auxiliary 12-bit digital-to-analog converter (DAC)
Configurable digital I/O port
Digital self-test function
The ADIS16203 offers two power management features for
managing system-level power dissipation: low power mode
and a configurable shutdown feature.
GENERAL DESCRIPTION
The ADIS16203 is a complete incline-angle measurement system
in a single compact package enabled by the Analog Devices, Inc.,
iSensor™ integration. By enhancing the Analog Devices iMEMS®
sensor technology with an embedded signal processing solution,
the ADIS16203 provides factory-calibrated, sensor-to-digital incline-
The ADIS16203 is available in a 9.2 mm × 9.2 mm × 3.9 mm
laminate-based land grid array (LGA) package with a temper-
ature range of −40°C to +125°C.
