Condition: Ta = â20°C to +75°C (regular specifications), Ta = â40°C to +85°C (wide-range
specifications)
Condition A: VCC = 2.7 to 5.5 V, AVCC = 2.7 to 5.5 V, VREF = 2.7 to AVCC, VSS = AVSS = 0 V,
Ï = 1 to 10 MHz
Condition B: VCC = 3.0 to 5.5 V, AVCC = 3.0 to 5.5 V, VREF = 3.0 to AVCC, VSS = AVSS = 0 V,
Ï = 1 to 13 MHz
Condition C: VCC = 5.0 V ±10%, AVCC = 5.0 V ±10%, VREF = 4.5 to AVCC, VSS = AVSS = 0 V,
Ï = 1 to 20 MHz
