Datasheet ADXRS453 (Analog Devices)

High Performance, Digital Output Gyroscope Data Sheet ADXRS453 FEATURES GENERAL DESCRIPTION Complete rate gyroscope on a single chip
The ADXRS453 is an angular rate sensor (gyroscope) intended
±300°/sec angular rate sensing
for industrial, instrumentation, and stabilization applications in
Ultrahigh vibration rejection: 0.01°/sec/g
high vibration environments. An advanced, differential, quad
Excellent 16°/hour null bias stability
sensor design rejects the influence of linear acceleration, enabling
Internal temperature compensation
the ADXRS453 to offer high accuracy rate sensing in harsh
2000 g powered shock survivability
environments where shock and vibration are present.
SPI digital output with 16-bit data-word
The ADXRS453 uses an internal, continuous self-test architec-
Low noise and low power
ture. The integrity of the electromechanical system is checked by
3.3 V to 5 V operation
applying a high frequency electrostatic force to the sense structure
−40°C to +105°C operation
to generate a rate signal that can be differentiated from the base-
Ultrasmall, light, and RoHS compliant
band rate data and internally analyzed.
Two package options Low cost SOIC_CAV package for yaw rate (z-axis) response
The ADXRS453 is capable of sensing an angular rate of up to
Innovative ceramic vertical mount package (LCC_V) for
±300°/sec. Angular rate data is presented as a 16-bit word that
pitch and roll response
is part of a 32-bit SPI message.
APPLICATIONS
The ADXRS453 is available in a 16-lead plastic cavity SOIC (SOIC_CAV) and an SMT-compatible vertical mount package
