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.

The Repeatability specifications represent analytical projections, which are based off of the following drift contributions and conditions: temperature hysteresis (−40°C
to +85°C), electronics drift (High-Temperature Operating Life test: +85°C, 500 hours), drift from temperature cycling (JESD22, Method A104-C, Method N, 500 cycles,
−40°C to +85°C), rate random walk (10 year projection), and broadband noise
2
Bias repeatability describes a long-term behavior, over a variety of conditions. Short-term repeatability is related to the in-run bias stability and noise density
specifications.
3
The digital I/O signals are driven by an internal 3.3 V supply, and the inputs are 5 V tolerant.
4
JEDEC Standard 22, Method A117. Endurance measured at −40°C, +25°C, +85°C, and +125°C.
5
These times do not include thermal settling and internal filter response times (340 Hz bandwidth), which may affect overall accuracy.
6
The sync input clock and internal sampling clock function below the specified minimum value, at reduced performance levels.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.

Extended exposure to temperatures outside the specified temperature
range of −40°C to +105°C can adversely affect the accuracy of the factory
calibration. For best accuracy, store the parts within the specified operating
range of −40°C to +105°C.

Although the device is capable of withstanding short-term exposure to
150°C, long-term exposure threatens internal mechanical integrity.
