Spehro Pefhany k 4 A will not work. How could I properly activate the Cd4093bcn datasheet trigger when the Zener is “on”?
If the input voltage is Vcc – 6. Sign up or log in Sign up using Google. Humpawumpa I added the schematic. I made a mistake and the trigger output is “sinking” the led instead of “sourcing” it, but the overall intention is preserved: Thanks for your answer! Is there a way to know if any other OpAmp would work or not, or dattasheet there a set of characteristics that would guide me to choose cd4093bcn datasheet fitting OpAmp for this application?
Cd4093bcn datasheet the dual version of the quad LM that Bimpelrekkie used. This is clearly spelled out in the datasheet. Questions Tags Users Badges Unanswered. In my 2nd circuit cd4093bcn datasheet zener makes a reference voltage, let’s assume it is 3 V. Pardon my lack of knowledge, but could you please tell me why the eatasheet work? It would be very useful to me, thanks! I made the zener cd4093bcn datasheet of D1 a bit lower, now the LED should switch on above 6.
I noticed you exchange the position between the Zener and its series resistor. If you derive the supply from the input voltage cd4093bcn datasheet have to take that into account. Also, do I assume correctly that altering the proportion beetween R6 and R5 I could cd4093bcn datasheet the values of the cd4093bcn datasheet voltage thresholds?
Sign up using Email and Password. Regarding the circuit with the Schmitt trigger, note that the levels of the Schmitt trigger are relative to cd4093bcn datasheet supply voltage so it is chasing a moving target the trigger level moves up as the supply goes up. Could you elaborate on that?
The thresholds are around 6. The needs more supply voltage and the input common mode range does not include ground. I am trying to design a circuit using an intermitent power source a bicycle hub generatorwhich is rectified and filtered, and regulated cd4093bcn datasheet 6,8V.

It is cd4093bcn datasheet what you need. The Schmitt trigger Cd4093bcn datasheet have rather poorly defined thresholds that are percentages of the supply voltage, not absolute voltages.
Quad 2-Input NAND Schmitt Trigger
What am I doing wrong? Yes, you can use an LM, it will work about as well in the above circuit, but put a cd4093bcn datasheet in parallel with the LED to keep the hysteresis about the same.
The LM is likely the cheapest op-amp in the world maybe a penny or cd4093bcn datasheet in volume and is suited for this application, especially the wide supply range. I did’nt understand your inversion.

The trig buffer means the IC properly connected to power rails. Make R7 smaller to increase the distance cd4093bcn datasheet the trigger levels. If you could the Schmitt trigger’s input to ground then that stays constant as the trigger level changes with the supply. Flip a Schmitt-Trigger when current flows through a Zener diode. Post as a guest Name. You can try something cd4093bcn datasheet this, which uses half of an inexpensive dual op-amp as a comparator.
