GENERAL DESCRIPTION

The ADIS16136 iSensor® is a high performance, digital gyro-

scope sensing system that operates autonomously and requires

no user configuration to produce accurate rate sensing data. It

provides performance advantages with its low noise density,

wide bandwidth, and excellent in-run bias stability, which enable

applications such as platform control, navigation, robotics, and

medical instrumentation.

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 +70°C.

As a result, each ADIS16136 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 ADIS16136 provides 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, using M2 (or 2-56 standard size)

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

pitch connector that supports electrical attachment to a printed

circuit board (PCB) or cable system.
