description

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.
