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

low-noise

instrumentation amplifiers with 1kHz low pass filters

provide

measurements

while
