SNOSAI2A –FEBRUARY 2005–REVISED MARCH 2013 www.ti.com APPLICATION HINTS The LM148 seriesarequad low power LM741 op amps. Intheproliferationofquad op amps, thesearethefirst to offerthe convenienceof familiar,easy to use operatingcharacteristicsof the LM741 op amp. In those applicationswhere LM741 op amps have been employed,theLM148 seriesop amps can be employed directly withno change incircuitperformance. The package pin-outsaresuch thattheinvertinginputofeach amplifierisadjacenttoitsoutput.Inaddition,the amplifieroutputsare locatedin the cornersof the package which simplifiesPC board layoutand minimizes package relatedcapacitivecouplingbetween amplifiers. The inputcharacteristicsof these amplifiersallowdifferentialinputvoltageswhich can exceed the supply voltages.Inaddition,ifeitheroftheinputvoltagesiswithintheoperatingcommon-mode range,thephase ofthe outputremainscorrect.Ifthenegativelimitoftheoperatingcommon-mode rangeisexceeded atbothinputs,the outputvoltagewillbe positive.For inputvoltageswhich greatlyexceed the maximum supplyvoltages,either differentiallyorcommon-mode, resistorsshouldbe placedinserieswiththeinputstolimitthecurrent. LiketheLM741, theseamplifierscan easilydrivea 100 pF capacitiveloadthroughouttheentiredynamic output voltageand currentrange.However, ifverylargecapacitiveloadsmust be drivenby a non-invertingunitygain amplifier,a resistorshouldbe placedbetween the output(and feedbackconnection)and the capacitanceto reducethephase shiftresultingfromthecapacitiveloading. The outputcurrentofeach amplifierinthepackage islimited.Shortcircuitsfroman outputtoeithergroundorthe power supplieswillnot destroythe unit.However, ifmultipleoutputshortsoccur simultaneously,the time durationshouldbe shorttopreventtheunitfrom beingdestroyedas a resultofexcessivepower dissipationin theIC chip. As withmost amplifiers,careshouldbe takenleaddress,component placementand supplydecouplinginorder toensurestability.For example,resistorsfromtheoutputtoan inputshouldbe placedwiththebody closetothe inputtominimize“pickup”and maximizethefrequencyofthefeedbackpolewhichcapacitancefromtheinputto groundcreates. A feedbackpoleiscreatedwhen the feedbackaround any amplifierisresistive.The parallelresistanceand capacitancefromtheinputofthedevice(usuallytheinvertinginput)toAC groundsetthefrequencyofthepole. Inmany instancesthefrequencyofthispoleismuch greaterthantheexpected3 dB frequencyoftheclosed loopgainand consequentlythereisnegligibleeffecton stabilitymargin.However, ifthefeedbackpoleisless thanapproximatelysixtimestheexpected3 dB frequencya leadcapacitorshouldbe placedfromtheoutputto the inputof the op amp. The valueof the added capacitorshouldbe such thatthe RC timeconstantof this capacitorand theresistanceitparallelsisgreaterthanorequaltotheoriginalfeedbackpoletimeconstant.
