Hello,
I am using the ADS1675 in WIDE-BANDWIDTH FILTER mode. I set the START PIN to high for continuous samp. I can see the DRDY pulse and the date out is correct. But , when outside of the board have EMI NOISE such as ESD in the air, the DRDY pulse is losed .The DRDY PIN and the DATA keep low. At this time , I can see the START PIN is keep high. If I do nothing ,this state will be continue . If I clear the START PIN to low and then set to hige ,the DRDY can see again ,and the samp data is correct again.
On my board have other chip ,such as DSP 、FPGA and so on,they are work good always.
