LM148JAN
Quad 741 Op Amps
General Description
The LM148 is a true quad LM741. It consists of four inde-
pendent, high gain, internally compensated, low power op-
erational amplifiers which have been designed to provide
functional characteristics identical to those of the familiar
LM741 operational amplifier. In addition the total supply
current for all four amplifiers is comparable to the supply
current of a single LM741 type op amp. Other features
include input offset currents and input bias current which are
much less than those of a standard LM741. Also, excellent
isolation between amplifiers has been achieved by indepen-
dently biasing each amplifier and using layout techniques
which minimize thermal coupling.
The LM148 can be used anywhere multiple LM741 or
LM1558 type amplifiers are being used and in applications
where amplifier matching or high packing density is required.
