Operational Amplifiers - National Semiconductor

The LM107 series LM107 LM207 LM307 are complete, general purpose operation- al Amplifiers with the necessary frequency compensation built into the chip. Advanced processing techniques make the input currents a factor of ten lower than industry stan- dards like the 709. Yet, they are a direct, plug-in replace- ment for the 709, LM101A and 741. The LM107 series offers the features of the LM101A which makes its application nearly foolproof. In addition, the de- vice provides better accuracy and lower noise in high im- pedance circuitry. The low input currents also make it partic- ularly well suited for long interval integrators or Timers sam- ple and hold circuits and low frequency waveform genera- tors. Further, replacing circuits where matched Transistor pairs Buffer the inputs of conventional IC op amps it CAN give lower offset voltage and drift at a lower cost. The LM107 is guaranteed over a b55Cto a125C temper- ature range, the LM207 from b25Cto a85C and the LM307 from 0Cto a70C By National Semiconductor Corporation
