The difference between ADC voltage supplies must be less than 100 mV, |VDD_HV_ADC1 − VDD_HV_ADC0| < 100 mV.

To be connected to emitter of external NPN. Low voltage supplies are not under user control—they are produced by an on-

chip voltage regulator—but for the device to function properly the low voltage grounds (VSS_LV_xxx) must be shorted to high

voltage grounds (VSS_HV_xxx) and the low voltage supply pins (VDD_LV_xxx) must be connected to the external ballast

emitter.

The low voltage supplies (VDD_LV_xxx) are not all independent.

VDD_LV_COR1 and VDD_LV_COR2 are shorted internally via double bonding connections with lines that provide the low

voltage supply to the data flash module. Similarly, VSS_LV_COR1 and VSS_LV_COR2 are internally shorted.

VDD_LV_REGCOR and VDD_LV_REGCORx are physically shorted internally, as are VSS_LV_REGCOR and VSS_LV_CORx.
