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.
