26.4 A/D Converter Characteristics
Table 26.17 shows A/D converter characteristics.
Table 26.17 A/D Converter Characteristics
Conditions: V_CC = PLLV_CC =3.3 V ± 0.3 V, AV_CC = 3.3 V ± 0.3 V, AV_CC = V_CC ± 0.3 V,
AV_ref = 3.0 V to AV_CC , V_SS = PLLV_SS = AV_SS = 0 V, T_a = –20°C to +75°C
(regular specifications), T_a = –40°C to +85°C (wide-range specifications),
When programming or erasing flash memory, T_a = –20°C to +75°C.
