dir9001 problems

Thank you, the first schematic is new to me so I tried that without any luck though. The second is from the datasheet which I based my own schematic on.

Regretfully, it seems I'm facing bad soldering or a broken chip. I soldered @ approx 350 celcius and afterwards I noticed from specs that the chip can withstand a max of 260 for 5 seconds...

Thanks for all your help guys!

On your schematic it looks like C1 is shorted, but I assume that that is not the case.
You don't describe what the distance is from your supply to the IC, but I strongly suggest to add bypass capacitors on the supply pins. Preferably very close to the IC.

Thanks for your input. In reality C1 isn't shortened but it is in the schematics, I'll fix that.

Yep, temperature can kill your chip... Use a good low-temperature solder and use 365°F temperature - the chip won't get hot if you limit the exposure time and quantity of solder.
For desoldering I use this.
The 63/37 ratio, known as eutectic solder has practically no plastic range, and melts almost instantly at 183°C (361°F).
