WebOct 8, 2005 · I'm just wondering if the LM1458 of ac current detector from Bowden's Hobby Circuit doesn't need any supply at all. Since its pin # 8 & 4 are not stated on the schematic diagram. Will it be possible to precisely set any desired current setting to activate relay (i.e 4 amps). What's the 1st op-amp used?
