Ordered 3pcs. The ICs were delivered in a factory package (a piece of tape from reel). Probably killed the first one by overheating (had to re-solder it three times in a row). The second one works OK so far at 4 Ohms load and Vcc=24V. Didn't tested the third one yet - but I think it should be OK too.
OK. I haven't tried the device yet. If he doesn't work well, I'll write.
