#104370 - why the UG? Responding to: ???'s previous message |
Inductive sensor gives always small signals, afer the inductive sensor you have to use unity gain amplifier ((OP07 op-amp ic) with +5v & - 5v dual supply).
and then you have use some inverting amplifer circuits, then you give to 74HC244 at the output of channel A, Why the unity gain amp? I would feed directly into a comparator configured with appropiate hysteresis. Erik |
