Programmable Dual-Axis Inclinometer/Accelerometer

The ADIS16201 is a complete, dual-axis acceleration and inclination angle measurement system available in a single compact package enabled by the Analog Devices iSensor™ integration. By enhancing the Analog Devices iMEMS® sensor technology with an embedded signal processing solution, the ADIS16201 provides factory calibrated and tunable digital sensor data in a convenient format that can be accessed using a serial peripheral interface (SPI). The SPI interface provides access to measurements for dual-axis linear acceleration, dual-axis linear inclination angle, 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 in-system offset calibration, along with convenient sample rate and bandwidth control.

The ADIS16201 offers the following embedded features, which eliminate the need for external circuitry and provide a simplified system interface:

* Configurable alarm function

* Auxiliary 12-bit ADC

* Auxiliary 12-bit DAC

* Configurable digital I/O port

* Digital self-test function

The ADIS16201 offers two power management features for managing system-level power dissipation: low power mode and a configurable shutdown feature.

The ADIS16201 is available in a 9.2 mm × 9.2 mm × 3.9 mm laminate-based land grid array (LGA) package with a temperature range of −40°C to +125°C.
