Hi,
  Yes I am using it to detect the variation in Earth's magnetic field

Best regards

Hi,

Are you using this to detect changes in the Earth's magnetic field or just
for a digital compass ?

Subject: [magnetometer] Comments needed for my 3-axis magnetometer (using
HMC1022) design

Hi all, i'm currently doing a 3-axis magnetometer using 2 HMC1022
chips. However, i'm unsure if my schematic design is appropriate. Can
somebody shed some light on my design or anyone that have experience in
using HMC1022.

Current stage for my breadboard prototype is on the sensor and
amplification module. I need advice on amplification factor, Vsupply
and whether i have setup correctly.

ps: i have uploaded my schematic under Files. (3-Axis Magnetometer
using HMC1022)

The Set/Reset Circuitry and the Offset Straps are not yet implemented
at this stage.

Thanks in advance.
