  • RE: LM2904: LM2904 about the output voltage issue

    Resolved
    Mickey, I do like the clarity of the OPA2131. This is one of the advantages of data sheet from this century. LM2904 could be updated in this way, however it is a many supplier device. If just one supplier changed to a new format then new customers would…

  • RE: TINA/Spice/LM4562: Working SPICE model for LM4562 (for use with LTspice XVII)

    Hello JC, thanks for your fast response. Regarding the pin order: normally, an OPAMP uses the pin order IN+/IN-/V+/V-/OUT - but in the LM4562.LIB subckt definition the inputs are swapped. The circuit is a rather simple signal amplifier which I…
