    Hello Sean,

    Does the application require the full 20MHz GBW or the 10V/us slew rate of the TSV994AIDT?

    If these parameters can be reduced, a P2P solution can be proposed. Included below is a comparison table highlighting the performance differences between the TLV9054, the TSV994, and the TLV9064. The TLV9054 is a close match to the TSV994 in most characteristics, with the GBW being notably less. The TLV9064 has 10MHz GBW, with a 6.5V/us slew rate compared to the 10V/us of the TSV994.

    I am happy to review the application to better understand any device specifications which are required.

    Let me know if you have any questions,

    Thank you,

    Jacob

    Hi Sean,

    there's almost never a 100% replacement. But the OPA4322 looks like a good candidate.

    Keep in mind, that the TSV994 seems to be a decompensated OPAmp and needs a minimum gain of 4.
