HD64F3437TF16 Datasheet, PDF (380/752 Pages) Hitachi Semiconductor – 12 V must not be applied to the S-mask model (single-power-supply specification), as this may permanently damage the device.

(R_in), an error will arise in the analog input pin voltage. Careful consideration is therefore required
when deciding the circuit constants.

A/D Conversion Precision Definitions: The H8/3437 Series A/D conversion precision definitions
are given below.
• Resolution
The number of A/D converter digital output codes
• Offset error
The deviation of the analog input voltage value from the ideal A/D conversion characteristic
when the digital output changes from the minimum voltage value B'0000000000 (H'000) to
B'0000000001 (H'001) (see figure 15.9).
• Full-scale error
The deviation of the analog input voltage value from the ideal A/D conversion characteristic
when the digital output changes from B'1111111110 (H'3FE) to B'1111111111 (H'3FF) (see
figure 15.9).
