Chopper-Stabilized Precision
Vertical Hall-Effect Latch
APPLICATIONS
It is strongly recommended that an external capacitor be con-
nected (in close proximity to the Hall-effect sensor IC) between
V_S
the supply and ground of the device to reduce both external noise
and noise generated by the chopper stabilization technique. As
shown in Figure 4, a 0.1 µF capacitor is typical.

sensors is available in:
