GENERAL DESCRIPTION

The ADIS16133 iSensor® is a high performance, digital gyro-

scope sensing system that operates autonomously and requires

no user configuration to produce accurate rate sensing data.

Key performance advantages include low noise density, wide

bandwidth, low variation over temperature, and excellent in-run

bias stability, all of which directly influence critical end perfor-

mance goals for platform stabilization, navigation, robotics,

and medical instrumentation systems.

This sensor system combines industry leading iMEMS® technology

with signal conditioning that optimizes dynamic performance. The

factory calibration characterizes the entire sensor signal chain for

sensitivity and bias over a temperature range of −40°C to +85°C.

As a result, each ADIS16133 has its own unique correction for-

mulas to produce accurate measurements upon installation. For

some systems, the factory calibration eliminates the need for

system level calibration and greatly simplifies it for others.

The ADIS16133 samples data at rates of up to 2048 SPS and

offers an averaging/decimation filter structure for optimizing

noise/bandwidth trade-offs. The serial peripheral interface (SPI)

and user register structure provide easy access to configuration

controls and calibrated sensor data for embedded processor

platforms.

The 36 mm × 44 mm × 14 mm package provides four holes for

simple mechanical attachment. Use M2 (or 2-56 standard size)

machine screws along with a standard 24-pin, dual row, 1 mm

pitch connector to support electrical attachment to a printed

circuit board (PCB) or cable system. The ADIS16133 provides

an operating temperature range of −40°C to +105°C.
