ADIS16133
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.
