Description:
...The magnitude of the set/reset current pulse depends onthe magnetic noise sensitivity of the system. If the minimumdetectable field for a given application is roughly 500μgauss in HMC1001/2, then a 3 amp pulse (min) is adequate.... ...?HMC2003 contains one HMC1001 and one HMC1002; together they make the 3-axis sensor. Three S/R straps are in serial, the total resistance is 4.5?.LINEAR MAGNETIC FIELD SENSORS10... ...a couple microseconds will ensure this. The circuits inFigures 8 and 9 are recommended for applications ofHMC1001/2 that require low noise and high sensitivitymagnetic readings....
