Hi

My knowledge seems to come to an end on the Legato schematics...
I don't get the LP corner freq 85KHz...
So simple question for you: Which RC components makes the 1st order LP filer?

Cheers,
Tom Think

Its the combination of the I/V resistors and the caps that are in parallel with them (or to GND you choice)

Which ones? I am in "tea spoon mode".
I would like to test out 100KHz corner and compare, thus need to calculate new C in the RC filter.
I guess the C1..4 are the C's in the RC filter, or?
And Rx, Ry, .., Rz are the R's in the RC filter?

Correct R1-4 and C1-4 are the values you need to consider for the filter..
