I have some problem with ADS8328 and I try to solve by myself but it still not work yet.
The problem is when I try to read data from ADC. After the CS is low, the SDO pin will oscillate until the falling edge of SCK.
The waveform is showed in the picture.
I decided to use auto-trigger and auto-channel mode. The connection of ADS8323 pins are
VBD = +3.3 v
VA = +5.0 v
EOC = No Use
CONST = Pull up to VBD with 5k Ohm
Ref-, COM, AGND, BDGND = Ground
Please give me the advice. What is the reason of this problem and how to solve it.
