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.
