The LM148, LM248, and LM348 are quadruple,
independent, high-gain, internally compensated
operational amplifiers designed to have operating
characteristics similar to the µA741. These
amplifiers exhibit low supply current drain, and
input bias and offset currents that are much less
than those of the µA741.
