TLV2170: Input common mode capacitor

Part Number: TLV2170

Hi team,

Would it be possible to obtain min/max values for input common mode capacitance value for TLV2170 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 Pol,

    We do not have an absolute min/max value for the input capacitances.  Worst-case would probably be +/-30% from the typical values but that's pretty unlikely seeing as the capacitance is largely based on the physical size of the input transistors and ESD cells which shouldn't change very much over process, lifetime, etc.
