Part Number: LMG1020

Hi,

Need some information regarding the input current requirement for pin IN- and what is the input capacitance for this pin ?. Thank you.

    Hello Harris,

    Thanks for reaching out!

    -------

    IN- and IN+ both have the same capacitance value of 1.3 pF.  (Please see Section 6.5 - Electrical Characteristics, of the datasheet)

    The input current requirement can be extrapolated with the internal input pull-down or pull-up resistances given in the same table.  This can be done by taking into account resistances, signal voltage, and VDD voltage for the IN- pin that is pulled up. 

    -------

    I hope this answered your question.  If so, please press the green button, otherwise feel free to follow up!

    Thanks,
