Which is Today's best Chip for chipAmp for Todays Audio Environment

for Class AB

 

[abraxalito]

Best SQ I've had from a chipamp has been from TDA8932.

 

[Destroyer OS]

That’s classD, I’m not sure I would call it a chipamp. But I’m also biased for our own EC7293. Straight chip though 7297 still seems supreme.

... best Chip for chipAmp for Todays Audio Environment

Could you specify 'best'?
Low cost? High reliability? High power output? Low noise floor? High efficiency?

Chipamps are only classAB in your estimation?

 

[FauxFrench]

I agree that for class D, TDA8932 is very good. So is TPA325x. Chip-amp or not, they are amplifiers in a single chip.
For class AB, LM3886 is among the best. LM1876 is fine as well for lower power levels. TDA729x are alternatives for varying power levels.
For finished DIY amplifier boards, Neurochrome has some very performant amplifiers. The EC7293 seems based on TDA7293s and using a similar composite amplifier concept as Neurochrome. These finished amplifier boards are for use "as is" as large experience has been put in for optimizing the performance.

I agree, I forgot to mention TPA3220/1 which has I think more potential (though less power ) than TPA325x due to the ability to use entirely external PSU regulation.

Well, this forum has them in seperate sections, so I’ll roll with it and say chipamps are not classD - likely classAB.

high power low noise floor

Thanks

actually I meant rather than Class D mainly AB

I like 3886...cheap, available, easy to use, reliable, almost fool proof, and it sounds decent as it is. Off course you can do all sorts of modifications, inverted, non-inverted, current source/current pump, parallel, nested...sky is the limit.

A good chip can provide mediocre performance in the wrong hands. Similarly, a decent chip can provide stellar performance in the right hands. You have to consider the entire circuit and not just the chip.

I get world-class performance from an LM3886 by applying error correction, for example.

[N-Channel]

LM1876 / LM4766 / LM4765

How about the Overture series of chip-amps from National- uh, i mean TI?

 

[ztwindwalker]

TPS6304

 

[oxoxbyx]

TPS6304

I can't found datasheet for this chip

could give me link or datasheet about this ?

 

[Leolabs]

To me,still the LM3875 but u need some tricks to pull the best out of it.

Anyway,TI no longer produce them but u might have chance to find someone who still got stock of 'em.

Hello

Can you say more about LM3886 error correction ?

Thank

look at neurochromes homepage !- then you know what he is talking about

Maybe this configuration under
https://www.schematicsforfree.com/a...ass AB/Bipolar/Composite Power Amplifiers.pdf
and
composite amplifiers
and
LM1875 in parallel configuration and used in a composite amplifier.
(turbocharged)
but with LM3886/TDA7294 and TI's last generation integrated operational amplifier OPA1611 could be the best solution for a non Class D configuration
