Hi everybody
Until now , I design my ADC circuits with myself but i have new project that i need to use 32bit SAR ADC and i want send data from this ADC to the Atmega32 (8bit). as you know designing the PCB or drive circuit for this ADCs is difficult and need time for finding errors and challenge with noise and ... So i make a decision that use the evaluation board but i havent any experience in it.
the LTC2500-32 is good for me and have a good features. and i found the DC2222A-A is the evaluation board of LTC2500-32 .but in datasheet i found this eval board make for some PDA .
I want use DC2222A-A stand alone without PDA . Can i do that or is it wisely ?!

You need to define "PDA," because neither of those references does so.

i talk about DC2026 , DC590 or DC890 . the boards that "DC2222A-A" can connect to them for reading or collecting data .

Can you duplicate the functions of those I/O boards? Do you need to?
A specification is called for here.
