description
The LM148, LM248, and LM348 are quadruple,
independent, high-gain, internally compensated
operational amplifiers designed to have operating
characteristics similar to the
μ
A741. These
amplifiers exhibit low supply current drain, and
input bias and offset currents that are much less
than those of the
μ
A741.
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
