• LM311: external resistor offset

  

  Keith Keller

  TI Thinks Resolved

  Part Number: LM311 Hello, We have a question on how we should calculate the offset based on the external resistors? In our case, we want to increase the offset on IN+, so should we assign more resistance to balance? E.g. 3k + 1.6k to balance, 3k+1…

  Hello Nattapong, Yes. The input voltage are referred to "GND" (midpoint of the supplies) in the tables. The LM311 is specified with +15 and -15V "split" supplies, both positive and negative. Though it is possible to use it with a single supply. …
