Product description: analog comparator LM339- SMD
Nnalog comparator with a supply voltage of 36 V or +/- 18 V. Case SO14 (SMD).
Technical characteristics of the comparator
- Supply voltage: 36 V or +/- 18 V
- Input voltage range of -0.3 V to 36 V
- Case: SO14
Inputs LM339
Example of analog comparator usage
The layout can be used instead of the sensor A/C (line detection sensors, opposite). On one input we give the signal from the sensors, on the other the reference results, which will be the threshold (e.g. with a potentiometer). At the output we receive a digital signal, which we can connect with a microcontroller pin. An corresponding layout can be created to compare distances.
