GENERAL DESCRIPTION  
through several built-in features, including a single-command  
auto-zero recalibration function, as well as configurable sample  
rate and frequency response. Additional features can be used to  
further reduce system complexity, including:  
The ADIS16250 is a complete, angular rate measurement  
system available in a single compact package enabled by Analog  
Devices, Inc., iSensor™ integration. By enhancing Analog  
Devices iMEMS® sensor technology with an embedded signal  
processing solution, the ADIS16250 provides factory calibrated  
and tunable digital sensor data in a convenient format that can  
be accessed using a simple SPI serial interface. The SPI interface  
provides access to measurements for the gyroscope, 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.  
Configurable alarm function  
Auxiliary 12-bit ADC and DAC  
Two configurable digital I°O ports  
Digital self-test function  
System power dissipation can be optimized via the ADIS16250  
power management features, including an interrupt-driven wake-up.  
The device range can be digitally selected from three different  
settings: ±±0ꢀ°sec, ±160ꢀ°sec, and ±20ꢀ°sec. Unique  
characteristics of the end system are accommodated easily  
The ADIS16250 is available in an 11 mm × 11 mm × 5.5 mm,  
laminate-based land grid array (LGA) package with a  
temperature range of −40ꢀC to +±5ꢀC.
