6.3.6 Magnetic Range Selection

Table 6-5 shows the magnetic range selection for the TMAG3001 device. The X, Y, and Z axes range can be selected with the X_Y_RANGE and Z_RANGE register bits.

Table 6-5 Magnetic Range Selection
RANGE REGISTER SETTING TMAG3001A1 TMAG3001A2 COMMENT
X, Y Axis Field X_Y_RANGE = 0h ±40mT ±120mT Higher resolution
X_Y_RANGE = 1h ±80mT ±240mT Higher range
Z Axis Field Z_RANGE = 0h ±40mT ±120mT Higher resolution
Z_RANGE = 1h ±80mT ±240mT Higher range
