I’m not reading it that way. 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. That means there is a small current flow out from the pin.
It appears to be reversed. I’m not following you.
If I remove the 2. Sign up or log in Sign up using Google. Vref is the high side of the 5 LED comparators in the datasheet block diagram.
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: Home Questions Tags Users Unanswered. Sign up using Facebook.

Setting 7 higher than ground biases the low side of the comparators, allowing them to turn on with a lower output from the amp. By “low side”, you’re referring to the inverting inputs of the comparators. Per AN’d datasheetPin 8 is the signal input pin, and it’s the internal Op amp’s positive input.
This circuit will light the LEDs as the input voltage on pin 8 increases relative to pin 7. It’s the DC bias determine the polarity.
Placing it at a higher voltage within the datasheet’s max specified V will both lower the datashset and raise the lower rail of the comparators in the block diagram. Indeed, it must in order for any of the LEDs to turn on!
As displayed, the LEDs go from fully off to fully on over roughly the entire turn range of the potentiometer. This makes sense, but why not a diode? Sign up using Email and Password. Very confusing terminology, since xatasheet inverting input can have a higher voltage than the noninverting input. The LED pins connect to the negative side of the LEDs, and the pins go low datasehet the output of the internal amp goes above Vref dropped by voltage dividing resistors at each comparator. There is also no discharge path with your arrangement.

Pin 8 accepts a positive input voltage.
Pin 8 is the signal input pin, and it’s the internal Op amp’s positive input. You should fix the capitalisation of sentences and electrical units ‘F’ for farad to improve legibility and credibility.

Capacitor with polarity can be used ac couple or blocking. Your description doesn’t agree with that in the datasheet. Most people use “low” to refer to either a lower voltage, or a lower position on the diagram. Email Required, but never shown.
