The ADXRS450 is an angular rate sensor (gyroscope) intended
for industrial, medical, instrumentation, stabilization, and other
high performance applications. An advanced, differential, quad
sensor design rejects the influence of linear acceleration, enabling
the ADXRS450 to operate in exceedingly harsh environments
where shock and vibration are present.
The ADXRS450 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 from
the baseband rate data and internally analyzed.
The ADXRS450 is capable of sensing 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.
The ADXRS450 is available in a cavity plastic 16-lead SOIC
(SOIC_CAV) and an SMT-compatible vertical mount package
(LCC_V), 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).
