Guaranteed

Note 1: These parameters are not characterized or tested in manufacturing.

2: No missing codes, limits based on characterization results.

3: These parameters are characterized but not tested in manufacturing.

4: Characterized with a 15 kHz sine wave.

5: The ADC module is functional at VBORMIN < VDD < VDDMIN, but with degraded performance. Unless

otherwise stated, module functionality is ensured, but not characterized.
