You might want to edit to explain your answer a bit more. Can someone explain what the reversed capacitor is doing here? So it determines the DC bias of the block capacitor’s polarity. Capacitor with polarity can be used ac couple or blocking.

Fadecomic 2 6. I’m not reading it that way. Passing Vin through a reverse capacitor seems to be potentially more prone to failure. However, if that’s the case, I can’t explain why reversing the capacitor doesn’t work, unless the actual polarity of the capacitor is backwards from what you think it is. It sounds like you’re trying to drive this circuit with a signal that includes a considerable DC bias, which explains why all of the LEDs light up right away when you remove short out the capacitor.


Your description doesn’t agree with that in the datasheet. How does doing anything to pin 7 or pin 8 affect datssheet That means there is a small current flow out from the pin. By “low side”, you’re referring to the inverting inputs of the comparators.

Vref is the high side of the 5 LED comparators in the datasheet block diagram.

That’s clear, because the input in my test circuit is DC. I’m not following you. Per AN’d datasheet.

Very confusing terminology, since the inverting input can have a higher voltage than the noninverting input. Post as vatasheet guest Name. I know the correct names, but I conversely find “inverting” and “noninverting” confusing when dealing dataaheet comparators, since those terms make more sense when dealing with op-amps. This circuit will light the LEDs as the input voltage on pin 8 increases relative to pin 7. Reverse biased capacitor on IC input pin Ask Question.


I will be certain to use them here from now on.

The potentiometer is clear, but the 2. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. Indeed, it must in order for any of the LEDs to turn on! Most people use “low” to refer to either a lower voltage, or a lower position on the diagram.

That is to say that the LEDs all come on at a much smaller turn of the potentiometer. Per AN’d datasheetPin 8 is the signal input pin, and it’s the internal Op amp’s positive input.

There is also no discharge path with your arrangement. It’s the DC bias determine the polarity. The diode will mess up ddatasheet response of the chip due to its forward voltage drop.
