The LM348 is a quadruple, independent, high-gain, internally compensated operational amplifier designed to have operating characteristics similar to the µA741. It consists of four internal built-in amplifiers. The amplifier exhibits low supply-current drain and input bias and offset currents that are much less than those of the µA741.
