Note: ADC functional device operation with either internal or external VREF < 2.4V is functional, but not characterized. ADC will function, but with degraded accuracy of approximately ~((0.06 * 2n) / VREF) LSB’s over full scale range, where n = #bits. ADC accuracy is limited by internal VREF accuracy plus drift, MCU generated noise plus users application noise/accuracy on AVDD, AVSS.
