The LM148consistsof four independent,high gain
internally compensated, low power operational
amplifiers which have been designed to provide
functionalcharacteristicsidenticaltothoseofthefa­miliar UA741 operational amplifier. In addition the
total supplycurrent forall fouramplifiersis compa­rable to the supply current of a singleUA741type
op amp. Other featuresincludeinput offsetcurrent
and input bias current which are much less than
thoseof a standardUA741.Also,excellentisolation
between amplifiers has been achieved by inde­pendentlybiasing each amplifier and using layout
techniqueswhichminimize thermal coupling.

The LM148can beusedanywheremultipleUA741
type amplifiers are being used and in applications
whereamplifier matchingor highpackingdensityis
required.
