ADIS16203:  Programmable 360° Inclinometer

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.
