DESCRIPTION
The LM148 consists of four independent,high gain
internally compensated, low power operational
amplifiers which have been designed to provide
functionalcharacteristics identical to those of the fa-
miliar UA741 operational amplifier. In addition the
total supply current for all four amplifiers is compa-
rable to the supply current of a single UA741 type
op amp. Other features include input offset current
and input bias current which are much less than
those of a standard UA741. Also, excellent isolation
between amplifiers has been achieved by inde-
pendently biasing each amplifier and using layout
techniques which minimize thermal coupling.
The LM148 can be used anywhere multiple UA741
type amplifiers are being used and in applications
where amplifier matching or high packing density is
required.
