OPA2810: OPA2180 to replace AD4898-2

hello Alex, 

Well there is a parametric cross reference here - 

http://www.ti.com/amplifier-circuit/op-amps/cross-reference.html

If I put that ADA part in, I get these results, either OPA2810 is not loaded in here or there are closer crosses -  let me note (looking at the ADA4898-2 datasheet)

1. At least in this case, the supply current is per channel

2. That input noise is very good for a unity gain stable part. 

So to get a quick compare to the OPA2810, put it in as a target part and it is in the database, basically about the same speed, little lower max supply, much higher input noise, much lower Icc, and RRIO

hi Michael Steffes

you can see the opa2810 spec is bad than ADA4898-2 ,right?

I need a op which spec is better than ADI,please advise it,thanks

well if you can handle just a little lower speed, the OPA2211A looks pretty good, at 1.1nV pretty close to the ADA4898-2. 

Or the OPA1611 is pretty close, 

That LMP8672 also looks pretty good, but we found recently its TINA model is not working. Perhaps the HSP team will fix that? 

Hello Alex,

Were you able to find a suitable replacement? Can you please share what specs you are trying to improve? What are the parameters needed for you design?

Best,
