Hi everyone, I bought an amplifier module. On the product page it was declared that it mounted an OPA657 but verifying upon arrival there is mounted a THS4001. I don't have much experience with these two opamps but comparing the datasheets, despite being electrically replaceable The OPA657 is newer and has better performance than the THS4001 (mainly bandwidth, gain and noise). I attach the technical sheets. Can you confirm or not that the THS4001 has lower performance than the OPA657? Thanks for your help.
