OPA2192: input common mode capacitors

Pol REYMOND

Part Number: OPA2192


Hi team,

Would it be possible to obtain min/max values for input common mode capacitance value for OPA2192 amplifier ?

My customer want to calculate the CMRR knowing the source resistor values (100k). There is only a typ value in the datasheet.

Thanks for your reply.

    Hi Reymond,

    Z_IC is usually provided as a typical value in the datasheet. We can obtain a variation of +/-30% from the typical value as a suggestion. It should not exceed this range.

    In this case it is +/-2pF from 6.4pF.

    I hope this helps for further calculations.

    Best,

    Miriam
