KXG03-1034 Digital Tri-axis Gyroscope/ Tri-axis Accelerometer Specifications
digital outputs accessed through I2C or SPI communication. The KXG03
sensor consists of a tri-axial micro machined gyroscope plus a tri-axial
accelerometer and an KXG03 packaged in a 3 x 3 x 0.9 mm 16-pin Land
Grid Array (LGA) package. The KXG03 is realized in standard CMOS
technology and features flexible user programmable gyroscope full scale
ranges of ±256, ±512, ±1024, and ±2048°/sec and user-programmable
±2g/±4g/±8g/±16g full scale range for the accelerometer. An auxiliary I2C
master serial interface exists for communication with up to 2 other sensors
to access data that can be accumulated in an internal 1024-byte FIFO buffer
and transmitted to the application processor. In addition, the KXG03 has an
embedded temperature sensor.
During operation, the gyroscope sensor elements are forced into vibration. When angular velocities are
applied about the sensing axes, vibration is transferred to sensing elements, causing capacitance
changes at the sensor electrodes. Acceleration sensing is based on the principle of a differential
capacitance arising from acceleration-induced motion of the sense element, which utilizes common
mode cancellation to decrease errors from process variation, temperature, and environmental stress.
Capacitance changes are amplified and converted into digital signals which are processed by a
dedicated digital signal processing unit. The digital signal processor applies filtering, bias and
sensitivity adjustment, as well as temperature compensation. The DSP also feeds back the driving
signal to ensure the proper sensor excitation.
The KXG03 series is designed to strike a balance between current consumption and noise
performance with excellent bias stability over temperature. These sensors can accept supply and
digital communication voltages between 1.8V and 3.6V.
