GENERAL DESCRIPTION
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.
The device range can be digitally selected from three different
settings: ±80°/sec, ±160°/sec, and ±320°/sec. Unique
characteristics 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
power management features, including an interrupt-driven wake-up.
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 −40°C to +85°C.
