General Description
The Honeywell HMC2003 is a high sensitivity, three-
axis magnetic sensor hybrid assembly used to measure
low magnetic field strengths. Honeywell’s most
sensitive magneto-resistive sensors (HMC1001 and
HMC1002) are utilized to provide the reliability and
precision of this magnetometer design. The HMC2003
interface is all analog with critical nodes brought out to
the pin interfaces for maximum user flexibility. The
internal excitation current source and selected gain and
offset resistors, reduces temperature errors plus gain
and offset drift. Three precision low-noise
instrumentation amplifiers with 1kHz low pass filters
provide accurate measurements while rejecting
unwanted noise.
