THS4121: Level differences in devices with specific marking

Franz Schellhase

Part Number: THS4121

Hi Team,

One of my customers has the following issue. Can you help them out?

We have used the IC mentioned in the subject several times on one board.
Now problems in the application occurred with level differences.
These problems occurred only in connection with the IC from figure 2.
Figure 1 shows the IC with which everything works correctly.
I only found the information for ASC as marker.
I would be very grateful for your help with this problem.

Thank you,

Franz

Hello Franz,

Adding onto Hasan's reply, were the two versions (Figure 1 and Figure 2) of the IC only tested with these two specific parts? Or was there a consistent pattern with these two versions across different parts? Also, would you be able to provide us with the exact part number (with type of package).

Thank you,

Sima
