3-Axis Digital Compass IC
HMC5883
The Honeywell HMC5883 is a surface mount multi-chip module designed for low
field magnetic sensing with a digital interface for applications such as low cost
compassing and magnetometry. The HMC5883 includes our state of the art,
high-resolution HMC118X series magneto-resistive sensors plus Honeywell
developed ASIC containing amplification, automatic degaussing strap drivers,
offset cancellation, 12-bit ADC that enables 1° to 2° compass heading accuracy.
The I
2
C serial bus allows for easy interface. The HMC5883 is a 3.0x3.0x0.9mm
surface mount 16-pin leadless chip carrier (LCC). Applications for the HMC5883
include Mobile Phones, Netbooks, Consumer Electronics, Auto Navigation
Systems, and Personal Navigation Devices.
The HMC5883 utilizes Honeywell’s Anisotropic Magnetoresistive (AMR) technology that provides advantages over other
magnetic sensor technologies. These anisotropic, directional sensors feature precision in-axis sensitivity and linearity,
solid-state construction with very low cross-axis sensitivity designed to measure both direction and magnitude of Earth’s
magnetic fields, from milli-gauss to 8 gauss. Honeywell’s Magnetic Sensors are among the most sensitive and reliable
low-field sensors in the industry.
