  • LM393-N: Difference input voltage and output switching

    Resolved
    Part Number: LM393-N Hi I'm using LM393-N as a basic comparator setup. the reference voltage (connected to pin 3) is set up through a basic voltage divider circuit from 1.930 - 2.723v Vin (connected to pin 2) as a voltage input can vary from 1.6…

  • RE: TLV7031: Zero crossing detection is not at 50% duty cycle

    Hi Rangel, your circuit has the disadvantage that the input signal exceeds the common mode input voltage range of TLV7031. This drives the TLV7031 into saturation and very probably causes the timing error. The datasheet of LM393-N shows a very nice circuit…
