Part Number: LMP7731

Where I can get the value of input capacitance for this OpAmp?
I want compare it with ADA4528-1 and this characteristic is important in an application.

    Hello Vlad,

    Yes, it appears the input capacitance information was not included in the LMP7731 datasheet and we don't have that information. I looked into the details of the LMP7731 front-end circuitry, supply range, and processing, and compared it to similar designs that have their common-mode and differential mode capacitances listed. An estimated range for the CDM and CCM capacitances is 3 pF minimum, 10 pF maximum.
