description/ordering information
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.
