GENERAL DESCRIPTION

The ADIS16260/ADIS16265 are complete angular rate meas-

urement systems 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 ADIS16260/ADIS16265 provide

factory-calibrated and tunable digital sensor data in a convenient

format that can be accessed using a simple SPI serial interface.

The ADIS16265 additionally provides an extended temperature

calibration. 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.

The device range can be digitally selected from three different

settings: ±80°/sec, ±160°/sec, and ±320°/sec. Unique charac-

teristics of the end system are accommodated easily 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:



Configurable alarm function



Auxiliary 12-bit ADC and DAC



Two configurable digital I/O ports



Digital self-test function



Digital sensor bandwidth selection

System power dissipation can be optimized via the ADIS16260/

ADIS16265 power management features, including an interrupt-

driven wake-up. The ADIS16260/ADIS16265 are available in an

11 mm × 11 mm × 5.5 mm, laminate-based land grid array

(LGA) package with a temperature range of −40°C to +105°C.
