High Performance,

Digital Output Gyroscope

Preliminary Technical Data

ADXRS450

FEATURES

GENERAL DESCRIPTION

Complete rate gyroscope on a single chip

300°/sec angular rate sensing

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.

High vibration rejection over a wide frequency range

Excellent 25°/hr null offset stability

Internally temperature compensated

2000 g powered shock survivability

SPI digital output with 16-bit data-word

Low noise and low power

3.3 V and 5V operation

−40°C to +105°C operation

Ultra small, light, and RoHS compliant

Two package options

The ADXRS450 utilizes 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.

Low cost SOIC_CAV package for yaw rate (Z-axis) response

Innovative ceramic vertical mount package, which can be

oriented for pitch, roll, or yaw response

The ADXRS450 is capable of sensing angular rate of up to

±±00ꢀ°sec. Angular rate data is presented as a 16-bit word, as

part of a ±2-bit SPI message.

APPLICATIONS

Rotation sensing medical applications

Rotation sensing industrial and instrumentation

High performance platform stabilization

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 (±.± V to 5 V) and temperature range (−40ꢀC to +105ꢀC).
