There are some key things to consider when purchasing an analog to digital converter for your PC.
The biggest drawback about the use of micro-controllers is that they usually require something of the user in terms of programming. These devices are, after all, designed to be extremely flexible in their utility and thus only come with minimal software support, often just a bootstrap program to allow access to the memory of the micro-controller by the main computer. Fortunately there are now some modules available which can be programmed in BASIC or C. The BASIC Stamp has been wildly popular for a couple of years now. This device allows you to easily program and utilize PIC technology. Some other BASIC programmable controllers are available with ADCs built into the units. Look at MicroMints Domino modules.
Be careful not to get a micro-controller board that requires additional equipment such as an EPROM programmer unless you are so equipped. Many of the micro-controllers require you purchase some kind of development board. Sometimes the board and software is much more expensive than the micro-controller itself.
If you decide to go the micro-controller route, be sure to pick up a book to familiarize yourself with the subject. The Handbook of Microcontrollers by Michael Predko is an 800 page volume which introduces you to several families of devices.
There are also a couple of ADCs in this list which are advertised as "oscilloscope probes" or something similar. For some applications where data must be collected at a high speed for short bursts of time these devices might be especially useful. Some of these listings are for semi-conductor manufacturers who do not supply finished ADC circuits. These listings are provided for those who would like to design their own ADC. Application notes are often available from these suppliers. These can be invaluable in creating your own designs.
