特性

  • µA741 Operating Characteristics
  • Low Supply-Current Drain . . . 0.6 mA Typ (per amplifier)
  • Low Input Offset Voltage
  • Low Input Offset Current
  • Class AB Output Stage
  • Input/Output Overload Protection
  • Designed to Be Interchangeable With Industry Standard LM148, LM248, and LM348

说明

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.
