Hello,

My ADC didn't work after a while.

After replacing the ADC7923 it works for some minutes but than the DOUT goes TRISTATE during converting operation.

see picture enclosed.

SPI signals from FPGA seems of, on the oscilloscope picture enclused only 0xFF is transfered to the ADC.

Could anybody help us?
