GENERAL DESCRIPTION

The ADIS16135 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 low noise density, wide

bandwidth, and excellent in-run bias stability, which are

enabling for applications such as platform control, navigation,

robotics, and medical instrumentation.

This sensor system combines industry-leading iMEMS® tech-

nology 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 ADIS16135 has its

own unique correction formulas to produce accurate measure-

ments upon installation. For some systems, the factory calibration

eliminates the need for system-level calibration and greatly

simplifies it for others.

The ADIS16135 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, 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 or cable system. The ADIS16135 provides an

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