The LM2907 is powered from 15V you have a 50Vppk sine wave input signal, centred at + 25v . The latter version is compatible with a 0 to lm2907 3 V input waveform by simply biasing the comparator' s inverting input ( pin 11. The 8- pins version is used with a variable reluctance pickup that has an output that swings datasheet above and below ground. See test circuit. hi Tamir, A pints couple of obvious pints points. The LM2907- N comes in two versions; one where the inverting input of the input comparator is grounded ( 8- pin device) pints , another where the inverting input is pints open can be biased to a voltage above 0 V ( lm2907 14- pin device).
