Texas Instruments TAS5261

What do folks make of this new class D integrated solution?

Certainly looks neat and offers respectable performance.

Any products confirmed as using these yet? And do you think its of any interest to the DIY market?

Mmmm.
Max power established at a THD of 10%... very professional

Perhaps Hypex, LCAudio and us, Coldamp, should rate our products at 50% higher power.

Bit out of context that.

• 125 W into 8 Ω at <0.09% THD+N
• 220 W into 6 Ω at 10% THD+N
• 315 W into 4 Ω at 10% THD+N

The 125w into 8ohm and less than 0.1% isn't bad at all for an integrated solution. Certainly better than the Gainclones and competitive with the higher power t-amps.

Yes, that's right, 0.1% at rated power is quite ok, but I was only saying that specifying 300w at 10% is next to useless and a bit tricky (marketing stuff, anyway).
They would have seemed much more serious if they had said 180W at 1% 4 ohm (it must be something like that). Nothing more...

The max switching frequency of the TAS5261 is stated as 432kHz, while TIs other chips have a max of only 192kHz. They obviously did something different with this chip.

I've ordered some samples, if I can solder these, I'll report back here on the result. Should be interesting.

@ericallan: I´ve ordered some samples too. Obviously PWM input is needed; did you figure out how to do that?

You can generate a PWM signal from an audio signal using a simple 555 timer. You can either figure out how to do it from the datasheets or search the web for a schematic.

Do you have an evaluation board or have you designed a board for this chip?

I'm wondering if this might do the trick:
