20.1.4 A/D Conversion Characteristics
Table 20.8 lists the A/D conversion characteristics.
Table 20.8 A/D Conversion Characteristics
Condition A: —In planning stage—
V_CC = AV_CC = 3.0 V to 5.5 V, V_ref = 3.0 V to AV_CC, V_SS = AV_SS = 0 V,
ø = 2 to 10 MHz, T_a = –20 to +75°C (regular specifications),
T_a = –40 to +85°C (wide-range specifications)
Condition B: V_CC = AV_CC = 5.0 V ± 10%, V_ref = 4.5 V to AV_CC, V_SS = AV_SS = 0 V,
ø = 2 to 20 MHz, T_a = –20 to +75°C (regular specifications),
T_a = –40 to +85°C (wide-range specifications)
