  • LF347: Difference Between LF347M vs LF347D

    Resolved
    Part Number: LF347 I have a board that uses many LF347M/NOPB devices but there is no stock at Digikey. There are many LF347DR devices. Can anyone tell what the difference is, or if there is a better replacement for the M/NOPB? John

  • RE: LF347: Lowest Positive Voltage on noninverting pin

    Resolved
    Hi Dillon, the LF347 is a dino OPamp and needs a minimum supply voltage is +/5V. The allowed common mode input voltage range is -1V...+1V then. The LF347 will not work properly with a 5V single supply. Kai

  • RE: NE555: How do I create a biphasic square wave generator circuit with variable frequency and magnitude?

    Kiryl, Clock output "wire" is just test point / informational. It doesn't do anything. Just measure the VF3 node with a oscilloscope , no load is needed because the output is a voltage signal. LM358 would work but the edges would be much slower. LF353…

  • RE: LF353-N: LF353-N Input Capacitance

    Resolved
    Richard, I believe the capacitance will be the same as LF347-N (quad) two samples. Cp is noninverting capacitance (to GND) Cn is inverting capacitance (to GND) Cd is input to input capacitance. LF347 LF347 Cp 3.3 pF 3.4 pF…
