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.

1 Extended exposure to temperatures outside of the specified temperature
range of −40°C to +85°C can adversely affect the accuracy of the factory
calibration. For best accuracy, store the parts within the specified operating
range of −40°C to +85°C.
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.

Preliminary Technical Data
PROGRAMMING AND CONTROL
CONTROL REGISTER OVERVIEW
The ADIS16260/ADIS16265 offer many programmable features
controlled by writing commands to the appropriate control
registers using the SPI. Table 8 provides a summary of these
control registers, which controls the operation of the following
parameters:
Calibration
Global commands
Operational control
Sample rate
Power management
Digital filtering
Dynamic range
DAC output
Digital I/O
Operational status and diagnostics
Self-test

CONTROL REGISTER STRUCTURE
The ADIS16260/ADIS16265 uses a temporary, RAM-based
memory structure to facilitate the control registers displayed in
Table 8. The start-up configuration is stored in a flash memory
structure that automatically loads into the control registers
during the start-up sequence. Each nonvolatile register has a
corresponding flash memory location, for storing the latest
configuration contents. Since flash memory has endurance
limitations, the contents of each nonvolatile register must be
manually stored to flash (note that the contents of the control
register contents are only nonvolatile when they are stored to
flash). The manual flash update command, made available
in the COMMAND register, provides this function. The
ENDURANCE register provides a counter that allows for
memory reliability management against the 20,000-write cycle
specification.
