LMV841: parasitic capacitance on supply PIN's V+ and V-

Hi,

do we have any information on the size of the parasitic caps @ V+ and V- ?  

I think it might be even better if we have any kind of load characterisitcs like  on the parasitic L and C for these PIN's.

Looking forward to your feedback, Bertram

    Hi Bertram,

    I was wondering what particular performance information you are looking for @ V+ and V- of LMV841. 

    LMV841 is 12V General Purpose Op Amp, Rail to Rail, Low Voltage series family, both Bipolar and CMOS devices.  For Op Amp power rails, it is typical low input impedance. You would prefer to have DC sources presented at the inputs of V+ and V- pins, bypass AC or ripple noises through bypass capacitors or parasitic capacitance of V+ or V- pins to ground. There maybe ESD protection diodes inside of V+ and V- rails. Are you trying to simulate a particular event in the part? 

    Best,

    Raymond
