Table 21-9 lists the D/A conversion characteristics.
Table 21-9 D/A 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 = 1 MHz to 8 MHz, Ta = –20°C to +75°C (regular
specifications), Ta = –40°C to +85°C (wide-range specifications)
Condition B: VCC = 3.15 V to 5.5 V, AVCC = 3.15 V to 5.5 V, VREF = 3.15 V to AVCC,
VSS = AVSS = 0 V, ø = 1 MHz to 13 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 = 1 MHz to 18 MHz, Ta = –20°C to +75°C (regular
specifications), Ta = –40°C to +85°C (wide-range specifications)
