I can not seem to get the ADS62P42 adc to continue to work. It work just fine for a while but then the outputs stop working. I am using an FPGA to interface with it and thought that perhaps upon reconfiguration of the FPGA the pins did something unusual and caused the outputs to stop working. Has anyone else experienced this and is there something I am overlooking. Just for information the current draw stays the same while not working and I have tried using the control pins to start the ADC pins tristated and then use the configuration registers to over ride the control pins. This did not work either. Also used CMOS outputs and LVDS happened to both. Have tried 3 now.
