D µA741 Operating Characteristics

D Low Supply-Current Drain . . . 0.6 mA Typ

(per amplifier)

D Low Input Offset Voltage

D Low Input Offset Current

D Class AB Output Stage

D Input/Output Overload Protection

D Designed to Be Interchangeable With

Industry Standard LM148, LM248, and

LM348

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.
