Passing Vin through a reverse capacitor seems to be potentially more prone to failure. It’s the DC bias determine the polarity. Datashheet it at a higher voltage within the datasheet’s max specified V will both lower the amplification and raise the lower rail of the comparators in the block diagram.

Home Questions Tags Users Unanswered. The diode will mess up the response of the chip due to its forward voltage drop. You might want to edit to explain your answer a bit more. Indeed, it must in order for any of the LEDs to turn on!
Very confusing terminology, since the inverting input can have a higher voltage than the noninverting input. To be clear, removing the capacitor doesn’t light up the LEDs all at once. The LED pins connect to the negative side of the LEDs, and the pins go low when the output of the internal amp goes above Vref dropped by voltage dividing resistors at each comparator.
I’m not following you.
That means there is a small current flow out from the pin. If I “correct” the orientation, the circuit does not work at all. Post as a guest Name.

How does doing anything to pin 7 or pin 8 affect that? Per AN’d datasheetPin 8 is the signal input pin, and it’s the internal Op datasgeet positive input. 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. This makes sense, but why not a diode?

Vref is the high side of the 5 LED comparators in the datasheet block diagram. There is also no discharge path with your arrangement. Right, I get that pin 7 is the output of the amp, but it’s part of the negative feedback loop on the amp. I am looking at the test circuits on the data sheet for the AN VU meter IC, and I cannot understand the connection to pin 8 in the following diagram: Pin 7 is the output of the internal amplifier, and pin 8 is its input, designed to accept a low-level AC input 57 mV for a 0-dB indication.

Have you tried a non-polarized capacitor e. Pin 8 accepts a positive input voltage.
By “low side”, you’re referring to the inverting inputs of the comparators. Most people use “low” to refer to either a lower voltage, or a lower position on the diagram. I’m not reading it that way.
