Analog to Digital Converter

I asked this earlier but they got lost in other Playstation
controller subjects. Since I'm planning on using the analog joysticks
of the PS2 controller, I have some questions about Analog to digital
converters.
1) any suggestions on easy to use ADC chips? would need input V of 0-
5V, I was thinking of the MAX1177, MAX1178, or MAX1188, 16 bit ADCs.
2) Do all ADCs do A->D and D->A? If not, then how would the stamp
send commands to the controller over the one data line if there is an
ADC between the controller and the stamp?
Thanks for the help!

1) Personally I found the LTC1298 12bit serial ADC easy to use.
There is a cheaper but similar alternative, the ADC0831 8bit ADC.
Both parts are available e.g. from the Parallax component shop,
accessories section.
2) Usually an ADC does not work as DAC, they are completely different
devices. Maybe there are some parts which incorporate both functions,
but I think this is the exception.
check out the link below for more info about the LTC1298:
