If anyone has this chip, on hand, please build up the circuit on the last page of the datasheet, and report back to us. I hate to burst anybodies bubble, but I see a problem.
With so many tried & true, tested, and readily available methods out there, I don't think I'll ever understand why people bother hacking around with inferior and hard to find IC's, unless they already happen to have the IC and wish to do something interesting with it.
