±300°/Sec Precision Angular Rate Sensor Data Sheet ADIS16135 FEATURES GENERAL DESCRIPTION Digital gyroscope system, ±300°/sec measurement range
The ADIS16135 iSensor® is a high performance, digital gyro-
In-run bias stability, ~6°/hour
scope sensing system that operates autonomously and requires
~11°/hour over temperature: −40°C to +85°C
no user configuration to produce accurate rate sensing data. It
Autonomous operation and data collection
provides performance advantages with low noise density, wide

bandwidth, and excel ent in-run bias stability, which are enabling
Start-up time: 181 ms; sleep mode recovery: 5 ms
for applications such as platform control, navigation, robotics,
Factory-calibrated sensitivity and bias
and medical instrumentation.
Calibration temperature range: −40°C to +85°C Single serial peripheral interface, SPI compatible
This sensor system combines industry-leading iMEMS® tech-
