• Operational Amplifier Series - Comparator Circuit

  9 May 2020   Tags: analogelectronic     embeddedsystems    
  From the datasheet, the LM741 can be operated in an open-loop configuration.The magnitude of the open-loop gain is typically large thus for a small difference between the non inverting and inverting input terminals, the amplifier output will be driven near the supply voltage. Without negative fee...   Read More
