IN1-
IN3+
IN3-
Hall effect sensor signal inputs.
These inputs are high when IN+ is greater than
IN- and low when IN- is greater than IN+.
Insert capacitors between the IN+ and IN– pins to
reduce noise.
An amplitude of over 50mVp-p and under
350mVp-p is desirable for the Hall input signals.
Kickback can occur in the output waveform if the
Hall input amplitude is over 350mVp-p.
