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: ±±0ꢀ/sec, ±160ꢀ/sec, and ±ꢁ20ꢀ/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 −40ꢀC to +105ꢀC.
