we are using ADS 1298 8-Channel 24-bit ADC With Integrated ECG Front End. when we power up device approximate 30 sec output will come exactly then noise will add all channels as per my observation when power up VCAP3 voltage level approximately 3V is there after that constantly decreasing voltage level when level draping the 2.82V or less than that then noise is over riding original ECG signal.
Please replay as early as possible
thanks and regards
