DESCRIPTION
The LM148consists of four independent,high gain
internally compensated, low power operational
amplifiers which have been designed to provide
functionalcharacteristicsidenticaltothoseofthefa-
miliar UA741 operational amplifier. In addition the
total supplycurrent for all fouramplifiers is compa-
rable to the supply current of a single UA741 type
op amp. Other featuresinclude input offsetcurrent
and input bias current which are much less than
thoseof astandardUA741.Also, excellentisolation
between amplifiers has been achieved by inde-
pendentlybiasing each amplifier and using layout
techniqueswhich minimize thermal coupling.
The LM148can be used anywhere multipleUA741
type amplifiers are being used and in applications
where amplifier matchingor high packing densityis
required.
