i've just finished my mini3 and wonder what opamp should i use for my music ( mostly vocal and violin, sometimes symphonic metal ).
PLz recommend some opamp ( i'm currently looking into burrbrown's products).
Thx in advance !!

I assume you're referring to the AMB Mini³?
 
AMB's instructions state the op-amps should be soldered to the PCB before any other components. This is to allow maximum ease of access to the pins. Soldering in the op-amps after all other components is harder, but not impossible.
 
AMB's instructions only recommend two op-amp combinations, one makes up the 'high-performance' edition and the other is the 'extended run-time' version. The difference is current draw and output. I personally went for the high-performance edition.

AMB mini3 that's wat i mean  
And i use the socket  to make it easier  swapping opamp  
But i don't know which opamp should i use for my gerne
 

 

[jr41]

The PCB mounts for the op-amps in the mini³ are surface mount, I was not aware you can get adapters for surface mount op-amps?
 
Also, I understand issues can arise if component lead lengths are too long. Something to do with inductance? This goes beyond my understanding though.

I wouldn't bother with pin lengths if they are not too long. It's not a RF aplication after all.

i've change the pcb a little bit so that i can solder the socket instead of the surface mount opamp

ad8559 in signal, opa690 in ground

 
i had this combination for quite some time before changing to hi performance edition. simply because vocal is not my main genre.

I would love to see some photos of your modification.

I can't find ad8559 opamp on the internet. would u mind giving me the link to it ?   thx

 

[PhaedrusX]

have you even tried the AD8397? it really is a very good little amp with the recommended opamp.
 
i remember reading a post by amb stating that the Mini3 is no longer really a Mini3 once other opamps are substituted.

 

[Beftus]

Not to mention that the AD8397 is capable of outputting much more current than most other opamps.

 

[tetracilin]

ad8397 sounds great  
i will get a pair and make a test
