yo fellow electronic geniuses 
. i am trying to build a simple metal detector, and have found an awesome simple schematic drawing while surfing the world wide web. however the main component is a cs209a proccessor chip. having spent hours searching for this wretched piece of kit, i have dicovered it has been dicontinued.
does anyone out there know of a chip that has the exact same characteristics and where i may purchase a couple incase i blow it up on my first attempt? pease say there is such a chip so i dont have to spend another week trying to find another lamens schematic.
i am part of an electrical HNC2 group so im not too clued up on heavy electronics. thank you. :wink:
