Forum Post: ADS124S06: About REFCOM pin connection in bipolar supply case

$

Part Number: ADS124S06 Tool/software: Hi all, I'm debugging a power supply issue on a board. It seems that the power supply chip sees low impedance (or a soft short) at the output, which limits the current and causes the output voltage to droop. This voltage rail is used as AVSS for the ADS124S06 . I've discovered that the REFCOM pin is connected to GND instead of AVSS . Could this cause such behavior? I'm suspecting there may be a low impedance path to GND in this case.
