GENERAL DESCRIPTION
The ADIS16250/ADIS16255 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 ADIS16250/ADIS16255 provide
factory-calibrated and tunable digital sensor data in a convenient
format that can be accessed using a simple SPI serial interface.
The ADIS16255 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.

RATE
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:
System power dissipation can be optimized via the ADIS16250/
ADIS16255 power management features, including an interrupt-
driven wake-up. The ADIS16250/ADIS16255 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 +85°C.
