hi Brian,

the EE is UPS and it work as V&I sampling signal conditioning.

I will double confirm with customer whether the current device is over spec

Since this is not an audio application, it would be better to ask the question to the liner amps team.

Hi Eric,

I filtered some of the parameters from the ANX device in our OpAmp portfolio, perhaps OPA810 is an option?: https://www.ti.com/amplifier-circuit/op-amps/products.html#p22typ=70;8000&~p78=In;Out

I'm also reassigning this thread to a more relevant team for further support.

Best regards,

Hi Ivan,

OPA2810 seems like a good alternative to the competitor part. If high output current is required, you may need to add a BUF634A at the output in a composite loop, as described in the BUF datasheet.

What is the application? We might be able to suggest a better part based for their needs instead of just a comparison to a competitor part.

Best regards,

Sean
