how to include loading effect and decoupling values?

[lowkb]

Hi all,

I'm using an ADC and i wanna first test its workability. Im trying to test it on a stand alone, wonder if any load effect will occured. i dun seems to get any output.

I using AD7478 and TLC0832, both are 8 bits serial out. dun seems to get any output if i connect to the infor on pins shown in the spec sheet. what shd i do?

you need to troubleshoot man!

Make sure you are clocking the converter correctly. Look at the serial output with an O'scope and make sure it is putting bits out. If it is, then you have a receive problem. If it is not, you could have a clocking or power supply problem.
