Dear TI Support,
ADS1299 data sheet (http://www.ti.com/lit/gpn/ads1299) does not specify voltage requirement for bypass capacitors, therefore one could assume that their operating voltage should not surpass the supply voltage.
But, a voltage measurement on VCAP3 pin (relative to AVSS) shows 6.86V. This is well above the supply voltage (AVDD to AVSS = 5V) and needs to be taken into consideration when selecting bypass capacitors.
Could you please point me to a document specifying the maximum operating voltage expected on VCAPx pins of ADS1299?
Best Regards,
Pawel
