GENERAL DESCRIPTION

The ADIS16251 is a complete, angular rate measurement

system available in a single compact package enabled by Analog

Devices iSensor™ integration. By enhancing Analog Devices

iMEMS® sensor technology with an embedded signal processing

solution, the ADIS16251 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.

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.

System power dissipation can be optimized via the ADIS16251

power management features, including an interrupt-driven

wake-up.

The device range can be digitally selected from three different

settings: ±2ꢀ0°sec, ±±ꢀ0°sec, and ±ꢁꢀ0°sec. Unique

characteristics of the end system are accommodated easily

The ADIS16251 is available in an 11 mm × 11 mm × 5.5 mm,

laminate-based land grid array (LGA) package with a

temperature range of −±ꢀ0C to +ꢁ50C.
