LM158/LM258/LM358/LM2904
LowPowerDualOperationalAmplifiers
GeneralDescription
TheLM158seriesconsistsoftwoindependent,highgain,internallyfrequencycompensatedoperationalamplifierswhichweredesignedspecificallytooperatefromasinglepowersupplyoverawiderangeofvoltages.Operationfromsplitpowersuppliesisalsopossibleandthelowpowersupplycurrentdrainisindependentofthemagnitudeofthepowersupplyvoltage.
Applicationareasincludetransduceramplifiers,dcgainblocksandalltheconventionalopampcircuitswhichnowcanbemoreeasilyimplementedinsinglepowersupplysystems.Forexample,theLM158seriescanbedirectlyoperatedoffofthestandard+5Vpowersupplyvoltagewhichisusedindigitalsystemsandwilleasilyprovidetherequiredinterfaceelectronicswithoutrequiringtheadditional±15Vpowersupplies.
TheLM358andLM2904areavailableinachipsizedpack-age(8-BumpmicroSMD)usingNational’smicroSMDpack-agetechnology.
