Ultra-Sensitive Dual-Channel Quadrature Hall-Effect Bipolar Switch
A3425
Typical Applications Operation
Quadrature output signal con
fi
guration. The outputs of the two output
channels have a phase difference of 90o when used with a properly
designed magnet that has an optimal pole pitch of twice the Hall ele-
ment spacing of 1.0 mm.
