Pin function
Hall bias negative-side pin.
In stop mode, the pin is open and Hall
bias is cut off.
Power supply pin.
The voltage supplied to this pin must be
stabilized to prevent ripple noise or other
noises from inputting to this pin.
AGC pin.
Controls the Hall amplifier gain according
to Hall input amplitude.
An external capacitor is used.
Speed discriminator pin.
Timing adjustment pin.
External CR for time constant circuit is
connected here.
