#173956 - Ratiometric Responding to: ???'s previous message |
The classic comparator circuit is actually ratiometric as well to the extent that the thresholds produced will be proportional to the supply voltage.
The threshold voltages specified for digital logic IC chip Schmitt trigger devices are quite loose (i.e. vary over a wide range) from part to part. If one is after an application that entails precision pick off points along a slow signal the IC chip solution is not usually suitable. Michael Karas |

| Couldn't this work just as well if one used a 40106? | 01/01/70 00:00 | |

| True .. it depends on what's needed | 01/01/70 00:00 | |
| Surprised at no response... | 01/01/70 00:00 | |
| Yes, another "student" who wants to be spoon-feeded... | 01/01/70 00:00 | |
| there was no question ... | 01/01/70 00:00 | |
| There was a question of sorts.... | 01/01/70 00:00 | |
| one day we may very well need just that | 01/01/70 00:00 | |
Surely 'almost' is key qualifier | 01/01/70 00:00 | |
