Pin function

Frequency characteristics correction

The capacitor connected between this pin and

ground stops closed-loop oscillation in the current

control system.

8

VH

The Hall elements are connected between this pin

and VCC1. The AGC circuit adjusts the Hall bias

current so that the coil output slope remains fixed.

Since the Hall amplifier common-mode voltage

range is reduced when a low voltage is used for

VCC1, the Hall elements should be connected in

parallel.

AGC

A capacitor is inserted between this pin and

ground. The AGC circuit controls the Hall bias

current so that the coil output slope remains fixed.
