1 These specifications apply when VRC33 is supplied externally, after disabling the internal regulator (VDDREG = 0).

2 ADC is functional with 4 V  VDDA  4.75 V but with derated accuracy. This means the ADC will continue to function

at full speed with no undesirable behavior, but the accuracy will be degraded.

3 The VDDF supply is connected to VDD in the package substrate. This specification applies to calibration package

devices only.
