thank you for this great info,
My goal is to obtain a "linear" going in the first 10 db of the scale. On page 21 of the data for LM3916 is show a schematic of a 17 segment ( quite good to me ) obtained cascoding 2 LM3916. but the first 5 step has a log increment, then the scale go linear with one db for led , I need the contrary of that configuration,
it seems to me is just an "how to" configuration issue.
