note 1) Indicates the minimum value when A/D clock = 2MHz (maximum clock frequency in 3V system).
Indicates the maximum value when A/D clock = 32kHz (minimum clock frequency in 3V system).
Note: • Be sure to use as V
• The A/D converter cannot be used when the S1C33L03 is used with a 2V power source.

V[000]h = Ideal voltage at zero-scale point (=0.5LSB)
V'[000]h = Actual voltage at zero-scale point
V[3FF]h = Ideal voltage at full-scale point (=1022.5LSB)
V'[3FF]h = Actual voltage at full-scale point
