LT1469
Go to linear.com and find out yourself.
I am using it in my CD player and the improvement over LT1364, a pair of AD843, and LM6172, is clear, in my opinion of course.

Ok, I do want someone to confirm my finding. Or give some comments regarding the specs, which I think are superb for I/V. They sound very clean and quite.
OPA627 is one of my favorite. However, I don't like it that much for I/V conversion because of it's BB laid-back sound (slightly coloued, IMO). LT1469's sound is as clean as OPA627's (That's quite an achivement), but is quieter and more neutral (is there such a thing as More Neutral). For the final audio output, LT1469 may lack output urrent (20ma) and some character. That's why I am using OPA627s there in the same CD player.
AD811 -- haven't compared yet.
I just put LT1364 in the I/V stage and sound became somewhat muddy and busy (read: noisy). It's another excellent opamp, IMO, with superb specs and decent price. However, for I/V conversion, LT1469 is a much better choice.

I do not completely understand your question. I am talking ahout a commercial cd player that has an I/V stage. I am just swapping the opamps -- no need for a daughter board or to hard wiring, just sockets.
If you are talking about single vs dual opamps, yes, for OPA627s, I used the Browndog adapters, since the original position was for two dual opamps.

Ah right !
Appologies for the confusion ! 😉
The reason I asked was because I'm looking for a cct to be able to use
I/V & modify my cd player.
BTW, what cd player did you modify with this ic ?
cheers,

It's an Ariston CD Player. That's the name, since it was the only cd player Ariston made in the early 90s.

I just send request to Linear Technology for free samples of LT1469. Maybe next week I'll can tell you my impressions.

The AD844 makes a very good I/V converter, and was used in a number of Sonic Frontiers dacs. It's a single op-amp, note that it is a current amplifier designed specifically for I/V conversion so I would recommend alternate devices for the none I/V (lpf stage usually) stages.
Hello Mudihan!
I put two LT1469 on my Philips 582 (1990).
Do you think they also need several days to be burned like most AD chips?

Tried 1469....
Samples from Linear came in today, i am using my modified MSB link i/v stage.
I have to say 1364 sounds much better...1469 sounds almost muted in comparism. Implementation wise, i have more than adequate bypassing, perhaps its not optimal for the 1469. But my growing collection of opamps dictate i am not going to change my config for one pair of opamps.

Hi, just wondering has anyone tried an AD825 as the I/V opamp, as I replaced my NE5532's with them on Browndog convertor boards and they absolutely killed the NE's, are they a good unit for this stage or is there better? I know they are very good as output opamps, but for the I/V stage?
