Part Number: THS4521
Other Parts Discussed in Thread: THS4551,

When moving THS4521 to THS4551 - are they directly replaceable with no schematic changes?

Thank you in advance

usually, but running a stability sim would be prudent as there are small differences in the Aol and Zol models

When switched to THS4551, not getting an inverse output, only direct on both channels (on 4521 outputs were ok) - any thoughts?

Hello Anatoli,

Would you be able to share the schematic and any simulation files?

Thank you,

Sima
