LM148 . . . FK PACKAGE

(TOP VIEW)

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.

The LM148 is characterized for operation over the

full military temperature range of –55°C to 125°C,

the LM248 is characterized for operation from

–25°C to 85°C, and the LM348 is characterized

for operation from 0°C to 70°C.
