NOTES:
1. ACLK = 1 µs.
2. A complete conversion cycle requires 16 ACLK periods, including five input sampling periods.
3. Relative accuracy is defined as the deviation of the code transition points from the ideal transfer point on a straight
line from the zero to the full scale of the device.
4. Stabilization time is defined as the time required for the A/D circuitry to stabilize after ADON is set to A logic “1”.
