#128690 - Improper load? Responding to: ???'s previous message |
Ralph said:
Pins 12 and 13 have 1 k resistor across them and not sure I engineer would do that either see schematic picture. This 1k resistor is needed to make the comparator skip, when the signal changes. But for this a varying current is needed to flow through this resistor, I guess. Maybe the comparator does not skip, because no regular load is connected to the circuit? Try to connect variable resistances from P1.2 and P1.3 to signal ground and play a bit with them. Kai |

Hhm, but this paralleling is widely used! | 01/01/70 00:00 | |
Parallel MOS transistors are fine | 01/01/70 00:00 | |
