A/D Conversion Characteristics

Table 21.9 lists the A/D conversion characteristics.

Table 21.9 A/D Conversion Characteristics

Condition A: VCC = AVCC = 2.7 V to 5.5 V, Vref = 2.7 V to AVCC, VSS = AVSS = 0 V,

φ = 2 to 10 MHz, Ta = –20 to +75°C (regular specifications),

Ta = –40 to +85°C (wide-range specifications)

Condition B: VCC = AVCC = 5.0 V ±10%, Vref = 4.5 V to AVCC, VSS = AVSS = 0 V,

φ = 2 to 20 MHz, Ta = –20 to +75°C (regular specifications),

Ta = –40 to +85°C (wide-range specifications)
