Part Number: ADS1247 Hello, I have a follow up question pertaining to ADS1247 . In my application I have 5 channels for temperature measurement and each channel has an ADS1247 chip. I am using the device for temperature measurements and using 4-wire configuration. During testing, I have only 2 channels connected with an RTD (or a resistor). I perform calibration (SYSOCAL and/or SYSGCAL) and after calibration is complete, the channels (that don't have a resistor or RTD connected) behave differently. For e.g. the output value on those ADC channel keep fluctuating randomly and more often than not, they indicate a negative number (ECXXXX - 24 bit output from the channel). In one case, the channel gets stuck to a particular value. When I try to connect a resistor across any of the unused channels, the ADC does not respond with the expected value and behaves in a similar manner as if nothing is connected across it's terminals. After I perform the reset (clearing OFC and/or FSR register values), the "unconnected" ADC channels start working properly. I wanted to understand the reason for the behavior and possible means to fix it. Thanks
