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.
