Notes:

1. “LSBs”, as used here, has a value of AVDD/256

2. Including sample time

3. It must be intended as the internal series resistance before the sampling capacitor

4. This is a typical expected value, but not a tested production parameter.

If V(i) is the value of the i-th transition level (0 < i < 254), the performance of the A/D converter has been valued as follows:

OFFS ET ERROR= deviation between the actual V(0) and the ideal V(0) (=1/2 LSB)

GAIN ERROR= deviation between the actual V(254) and the ideal V(254) (=AVCC-3/2 LSB)

DNL ERROR= max {[V(i) - V(i-1)]/LSB - 1}

INL ERROR= max {[V(i) - V(0)]/LSB - i}

ABS. ACCURA CY= overall max conversion error

S/N ratio has been valued by sampling a sinusoidal input waveform and then calculating its Fast Fourier Transform.

2. Absolute accuracy: 2.5 LSB at 3V.
