17.2.3 A/D Conversion Characteristics
Table 17-7 lists the A/D conversion characteristics.
Table 17-7 A/D Converter Characteristics
Condition A: VCC = 2.7 V to 5.5 V, AVCC = 2.7 V to 5.5 V, VREF = 2.7 V to AVCC,
VSS = AVSS = 0 V, ø = 2 MHz to 8 MHz, Ta = –20°C to +75°C (regular
specifications), Ta = –40°C to +85°C (wide-range specifications)
Condition B: VCC = 3.0 V to 5.5 V, AVCC = 3.0 V to 5.5 V, VREF = 3.0 V to AVCC,
VSS = AVSS = 0 V, ø = 2 MHz to 10 MHz, Ta = –20°C to +75°C (regular
specifications), Ta = –40°C to +85°C (wide-range specifications)
Condition C: VCC = 5.0 V ± 10%, AVCC = 5.0 V ± 10%, VREF = 4.5 V to AVCC,
VSS = AVSS = 0 V, ø = 2 MHz to 16 MHz, Ta = –20°C to +75°C (regular
specifications), Ta = –40°C to +85°C (wide-range specifications)
