Hey Guys
Does anyone know if the LM311N is sort of an "inverted" comparator? As far I know, when the voltage at the + terminal is larger than the - termainl, the output should goto +ve rail , however, when I tried with the LM311N, it was inverted (ie, gave me -ve rail)
furthermore, it wasn't exactly 0v or 5v (i'm using 5v battery, +ve side conencted to V+ , and negative side to V-, not to the GROUND pin,) the "low" state was giving me 0.8 v, and the high state was giving me around 3.4 v.. is there a reason for this offset?
