Datasheet

Mounting information
The board has two mounting holes on the logic side of the board. These mounting holes are 0.5" apart
and are designed for #2 screws.
Filtering the output
The IC has an internal filter resistance of 1.7 kΩ, and the carrier board includes a 1 nF filter capacitor,
which produces a low-pass RC filter with a 90 kHz cutoff. You can improve sensing system accuracy
for low-frequency sensing applictations by adding a capacitor in parallel with the integrated 1 nF
capacitor across the pads marked “filter” on the bottom silkscreen (this capacitor is labeled C2b in the
schematic below). The frequency F that the filter will attenuate to half its original power is given by:
F = 1 / (2πRC) = 1 / (11kΩ * (1 nF + Cf))
where Cf is the value of the capacitor added to the filter pads.
