Default Free sample advice

I have just recieved a free sample from Analog Devices.

I have got 2 x ADAU1590 chips. The description on site says....

The ADAU1590 is a 2-channel, bridge-tied load (BTL) switching audio power amplifier with an integrated Σ-Δ modulator.

Has anybody used or done anything with this chip? I nearly fell off my chair when I saw how small they are.

Yes, i ordered them simply because i can and they were free. Be nice if I can actualy use them though.

If anybody has hints tips or links it would be greatly appreciated.

Chip size is about 1/4" square right?
Same problem, different chip. I found an local store that carries these:
SchmartBoard - The world's best circuit prototyping system
Down side is those free chips will end up costing you ~$10 USA just for the prototype board.

I've found other prototype boards that give you a number of different formats on a larger size board but they start at ~$15 and I don't know if they support soldering the way the Schmartboard does.
