The ADIS16130 is a low noise, digital output angular rate sensor
(gyroscope) that provides an output response over the complete
dynamic range of ±250o/sec.
Its industry-standard serial interface and register structure provide
a simple interface that is supported by most MCU, DSP, and FPGA
platforms.
By implementing a unique design, the device provides superior
stability over variations in temperature, voltage, linear acceleration,
vibration, and next-level assembly. In addition, the surface-micro-
machining technology used to manufacture the device is the
same high volume BiMOS process used by Analog Devices, Inc.,
for its high reliability automotive sensor products.
Features include a temperature output that provides critical
information for system-level calibrations and a digital self-test
feature that exercises the mechanical structure of the sensor and
enables system-level diagnostics.
The package configuration is a 36 mm × 44 mm × 16 mm
module with a standard 24-lead connector interface.
