3-Axis Digital Compass IC
HMC5843
The Honeywell HMC5843 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 HMC5843 includes our
state of the art 1043 series magneto-resistive sensors plus Honeywell
developed ASIC containing amplification, strap drivers, offset cancellation,
2
12-bit ADC and an I C serial bus interface. The HMC5843 is in a 4.0 by 4.0
by 1.3mm surface mount leadless chip carrier (LCC). Applications for the
HMC5843 include Consumer Electronics, Auto Navigation Systems,
Personal Navigation Devices, and Magnetometers.
The HMC5843 utilizes Honeywell’s Anisotropic Magnetoresistive (AMR) technology that provides advantages over other
magnetic sensor technologies. The 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 tens of
micro-gauss to 6 gauss. Honeywell’s Magnetic Sensors are among the most sensitive and reliable low-field sensors in the
industry.
Honeywell continues to maintain product excellence and performance by introducing innovative solid-state magnetic
sensor solutions. These are highly reliable, top performance products that are delivered when promised. Honeywell’s
magnetic sensor solutions provide real solutions you can count on.
