LM148/LM248/LM348 Quad 741 Op AmpsGeneral DescripTIonThe LM148 series is a true quad 741. It consists of fourindependent, high gain, internally compensated, low poweroperaTIonal amplifiers which have been designed to providefuncTIonal characterisTIcs identical to those of the familiar741 operational amplifier. In addition the total supply currentfor all four amplifiers is comparable to the supply current of asingle 741 type op amp. Other features include input offsetcurrents and input bias current which are much less thanthose of a standard 741. Also, excellent isolation betweenamplifiers has been achieved by independently biasing eachamplifier and using layout techniques which minimize thermalcoupling.The LM148 can be used anywhere multiple 741 or 1558 typeamplifiers are being used and in applications where amplifiermatching or high packing density is required. For lowerpower refer to LF444.
