    Hi, I have two questions about the graph(Figure-24) in the LMV342 data sheet. Could you please see the following question? Could you please teach me? Thanks in advance, Toshiya

    Hello Thomas-san, Thanks for your prompt response and explanation. It is helpful for me. Well, about the value of RF and RG. If gain is -1000V/V, I think RF=1000kohm and RF=1kohm or RF=100kohm and RG=100ohm. Which is correct? Could you please teach me? Regards, Toshiya

    Our customer trying to design an sensing circuit with LMV342 as below. They want to know the output impedance of this circuit and LMV342 itself. I think the the output impedance of this circuit is 100Ohm, but I can't find the output impedance of LMV342 in the datasheet. Please let me know...

    Hiroshi-san; There seems to be no output impedance specification in its data sheet and TI does not provide a SPICE or TINA model for this device. There fore the output impedance of your circuit is not determined-- but for sure it is not 100 ohms, due to the action of the negative feedback C1 R2.

    Hello Ron-san, Thank you for your information, it is very useful. The customer recognize that circuit is not good, and trying to simulate with TLV342 model. Thanks and best regards, Hiroshi Sato
