  • 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: 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…

  • 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 Cn 3.5 pF 3.7 pF …

  • RE: Integrator up to 1MHz

    Kimmo, I believe that you are using an LF347, correct? There is a discrepancy in your posting but your schematic indicates LF347. This device does not have sufficient gain-bandwidth to provide a good integrator response to 1MHz. A possible replacement…
