DESCRIPTION The LM148 consists of four independent, high gain internally compensated, low power operational amplifiers which have been designed to provide functional characteristics identical to those of the familiar UA741 operational amplifier. In addition the total supply current for all four amplifiers is compatible 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 independently biasing each amplifier and using layout techniques qhich minimize thermal coupling. The LM148 can be used anywhere multiple UA741 type amplifiers are being used and in applications where amplifier matching or high packaing density is required. ORDER CODE
