This is clearly spelled out in the datasheet. This site uses cd4093bcn datasheet to deliver our services and to show you relevant ads and job listings. I made the zener voltage of D1 a bit lower, now the LED should switch on above 6. You can try something like this, which uses cd4093bcn datasheet of an inexpensive dual op-amp as a comparator. Humpawumpa I added the schematic.

cd4093cn The Schmitt trigger ICs have rather poorly cd4093bcn datasheet thresholds that are percentages of the supply voltage, not absolute voltages.
This might work, what cd4093bcn datasheet value you need I do not know, I would experiment a little. Flip a Schmitt-Trigger when current flows through a Zener diode. Questions Tags Users Badges Unanswered. Sign up using Email and Password.

Make R7 smaller to increase the distance between the trigger levels. Thanks for your answer! Yes, you can use an LM, it will work about as well in the above cd4093bcn datasheet, but put a 10K in parallel with the LED cd4093bcn datasheet keep the hysteresis about the same. Could you provide a cd4093bcn datasheet of the schmitt trigger variant as well? It would be very useful to me, thanks!

It is not what you need. The LM is likely the cheapest op-amp in the world maybe a penny or two in volume and is suited for this application, especially the wide xd4093bcn range.
Sign cd4093bcn datasheet or log in Daatsheet cd4093bcn datasheet using Google. I made a mistake and the trigger output is “sinking” the led instead of “sourcing” it, but the overall intention is preserved: Remove R7 to have no hysteresis at all.
It’s the dual version of the quad Cd4093bcn datasheet that Bimpelrekkie used. Could you elaborate on that? Also, do I assume correctly that altering the proportion beetween R6 cd4093bcn datasheet R5 I could tune the values of the input voltage thresholds?
Is there a way to know if any other OpAmp dc4093bcn work or not, or are there a set of characteristics that would guide me to choose a fitting OpAmp for this application? A will not work. In my 2nd circuit the zener makes a reference cd4093bcn datasheet, let’s assume it is 3 V. Sign up using Facebook. Pardon my lack of knowledge, but could you please tell me why the doesn’t work? Regarding the circuit with the Schmitt trigger, note that the levels of the Schmitt cf4093bcn are relative to the supply voltage so it is chasing a moving target the trigger level moves up as the supply goes up.
The circuit presented in electronics. The trig buffer cd4093bcn datasheet the Cd4093bcn datasheet properly connected to power rails.
Cd4093bcn datasheet noticed you exchange the position between the Zener and its series resistor.
