After checking with a working PCB, we are getting -2.5V on BIAS and 0V on SRB.
Our BIAS configuration is as mentioned in the Figure 72 of the datasheet.
In daisy chain configuration, we follow the configuration mentioned in this post : https://e2e.ti.com/support/data-converters-group/data-converters/f/data-converters-forum/561788/ads1299-connecting-bias-and-reference-electrodes-with-multiple-ads1299
In a standalone confguration, the voltages are correct but if we connect the PCBs in a daisy chainn configuration the voltages are around -1V on BIAS and -0.5V on SRB. What could be the possible reason ?
