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-
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, ±180°
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.
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.
The ADIS16203 offers the following embedded features that
eliminate the need for external circuitry and provide a simplified
system interface:
• Configurable alarm function
• 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.
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.

1 This sensor relies on the earth’s gravity to provide accurate incline angle measurements. The axis of rotation must be perpendicular to the earth’s gravity to maintain the
factory-calibrated accuracy of the sensor.
2 Guaranteed by design.
3 Endurance is qualified as per JEDEC Standard 22 Method A117 and measured at −40°C, +25°C, +85°C, and +125°C.
4 Retention lifetime equivalent at junction temperature (TJ) 55°C as per JEDEC Standard 22 Method A117. Retention lifetime decreases with junction temperature.
