The ADIS16201 is a complete, dual-axis acceleration and The ADIS16201 offers the fol owing embedded features, which inclination angle measurement system available in a single eliminate the need for external circuitry and provide a simplified compact package enabled by the Analog Devices iSensor™ system interface: integration. By enhancing the Analog Devices iMEMS® sensor • technology with an embedded signal processing solution, the Configurable alarm function ADIS16201 provides factory calibrated and tunable digital • Auxiliary 12-bit ADC sensor data in a convenient format that can be accessed using a • Auxiliary 12-bit DAC serial peripheral interface (SPI). The SPI interface provides access to measurements for dual-axis linear acceleration, dual- • Configurable digital I/O port axis linear inclination angle, temperature, power supply, and • Digital self-test function one auxiliary analog input. Easy access to calibrated digital sensor data provides developers with a system-ready device, The ADIS16201 offers two power management features for reducing development time, cost, and program risk. managing system-level power dissipation: low power mode and a configurable shutdown feature. Unique characteristics of the end system are accommodated easily through several built-in features, such as a single The ADIS16201 is available in a 9.2 mm × 9.2 mm × 3.9 mm command in-system offset calibration, along with convenient laminate-based land grid array (LGA) package with a sample rate and bandwidth control. temperature range of −40°C to +125°C.
