Digital Tri-axis Magnetometer/
Tri-axis Accelerometer
Specifications
Product Description
KMX62 is a 6 Degrees-of-Freedom inertial sensor system that features
16-bit digital outputs accessed through I
2
C communication. The KMX62
sensor consists of a tri-axial magnetometer plus a tri-axial accelerometer
coupled with an ASIC. It is packaged in a 3 x 3 x 0.9mm Land Grid Array
(LGA) package. The ASIC is realized in standard 0.18um CMOS
technology and features flexible user programmable ±2g/±4g/±8g/±16g
full scale range for the accelerometer. Accelerometer and Magnetometer
data can be accumulated in an internal 384 byte FIFO buffer and
transmitted to the application processor.

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.
Magnetic sensing is based on the principle of magnetic impedance. The magnetic sensor detects very
small magnetic fields by passing an electric pulse through a special electron spin aligned amorphous
wire. Due to the high Curie temperature of the wire, the sensor’s thermal performance shows excellent
stability.
Noise performance is excellent with bias stability over temperature. Bias errors resulting from
assembly can be trimmed digitally by the user. These sensors can accept supply voltages between
1.7V and 3.6V, and digital communication voltages between 1.2 and 3.6V.
