My customer has the following question:
I bought an EVM board for the chip and found the sampling noise to be very low. I decided to duplicate exactly the EVM board's input circuit on the second rev of my board. However, there's a problem with a part on the EVM board: the datasheet calls out a certain ferrite bead for the input circuit (Panasonic EXC-ML32A680U). This part is obsolete and unavailable, but that's not the problem; Arrow lists an equivalent. The problem is: the Panasonic part is a 1206 package size, but the actual part on the board looks like it's roughly 0603 size, so it can't be the Panasonic part. I attached a picture of the eval boad - L30 and L31 are clearly about the same size as R59 and R60, and those resistors are obviously 0603 size (and are called out as such in the bill of materials).
What was the actual part used on the board?
Thanks for your help with this!
