Data Sheet
ADXRS800
FEATURES
GENERAL DESCRIPTION
Excellent null offset stability over temperature
High vibration rejection over a wide frequency range
2000 g powered shock survivability
SPI digital output with 16-bit data-word
Low noise
Continuous self-test
Fail-safe functions
Temperature sensor
3.3 V and 5 V operation
The ADXRS800 is an angular rate sensor (gyroscope) intended
for automotive electronic stability control, vehicle rollover
detection, and other high performance applications. An advanced,
differential, quad-sensor design rejects the influence of linear
acceleration, enabling the ADXRS800 to operate in exceedingly
harsh environments where shock and vibration are present.
The ADXRS800 uses an internal, continuous self-test archi-
tecture. The integrity of the electromechanical system is checked
by applying a high frequency electrostatic force to the sense
structure to generate a rate signal that can be differentiated
−40°C to +105°C operation
Small, low-profile industry standard SOIC package provides
yaw rate (Z-axis) response
from the baseband rate data and internally analyzed.
The ADXRS800 is capable of sensing an angular rate of up to
300°/sec. Angular rate data is presented as a 16-bit word, as
part of a 32-bit SPI message.
Innovative ceramic vertical mount package (VMP) provides
pitch and roll rate response
Qualified for automotive applications
The ADXRS800 is available in a cavity plastic SOIC-16 and
an SMT-compatible vertical mount package and is capable of
operating across both a wide voltage range (3.3 V to 5 V) and
temperature range (−40°C to +105°C).
