Biaxial magnetic field sensor application circuit as shown in FIG. Using a biaxial magnetic sensor HMC1002, two AMP04 (A1, A2), the magnetic field can simultaneously measure th
e X-axis direction and the Y-axis direction. HMC1002 two voltage signals outputted respectively after A1 and A2 amplification, then the analog input and the reference terminal 12 bit A/D converter TLC2543, and then connected via the interface circuit P. MAX662A is a highly efficient DC/DC converter can be raised to + 5V power supply + 10V, as the drive power IRF7105. Pulse current driver input signal from the P, the output is sent to the HMC1002 S/R + terminal (pin 16). Figure C3 tantalum capacitors should be used.
