1 / 18 page  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.
