2、e ?Input/Output Overload Protection ?Designed to Be Interchangeable With National LM148, LM248, and LM348descriptionThe LM148, LM248, and LM348 are quadruple, independent, high-gain, internally compensated operational amplifiers designed to have operating characteristics similar to the A741. These a
3、mplifiers exhibit low supply current drain, and input bias and offset currents that are much less than those of the A741.The LM148 is characterized for operation over the full military temperature range of 55C to 125C, the LM248 is characterized for operation from 25C to 85C, and the LM348 is charac
