Hall-effect sensor inputs

When IN+ > IN–, the input is seen as a high level, and

when the reverse condition is true, it is seen as a low

level.

An amplitude of over 50 mVp-p (differential) is desirable

as the Hall input signal. If noise on the Hall signals is a

problem, insert capacitors between the IN+ and IN- inputs.
