Hello everyone. I'm new here but i need some help as to what each of the feet do within the IC. I've tried data sheets but they are too complicated and i don't understand most of it. Can someone briefly explain what each foot does please?

Thanks

hi,
Read thru the first 3 pages of this pdf.

If you have specific questions about a pin/foot, just ask.

What is the point of the reference voltage though?? Please describe with not many technical words please

 

Rlo and Rhi set the lower and upper voltage limits of the comparators, Refout is the output of the internal voltage regulator, Radj is the regulator adjusment pin, Sig is the input for the comarators, Mode sets the Leds in Bar or Dot mode,

The internal reference regulator is just an Lm317, used to set the upper and lower limits on the Rhi, Rlo pins, it can be omitted and external voltages placed on the pins to set the limits, however it also sets the current limit on the led output pins.

hope that answers most of your question
