Condition A: V_CC = 2.7 V to 5.5 V, AV_CC = 2.7 V to 5.5 V, V_REF = 2.7 V to AV_CC,
V_SS = AV_SS = 0 V, ø = 2 MHz to 8 MHz, T_a = –20°C to +75°C (regular
specifications), T_a = –40°C to +85°C (wide-range specifications)
Condition B: V_CC = 3.0 V to 5.5 V, 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 MHz to 10 MHz, T_a = –20°C to +75°C (regular
specifications), T_a = –40°C to +85°C (wide-range specifications)
Condition C: V_CC = 5.0 V ± 10%, AV_CC = 5.0 V ± 10%, V_REF = 4.5 V to AV_CC,
V_SS = AV_SS = 0 V, ø = 2 MHz to 16 MHz, T_a = –20°C to +75°C (regular
specifications), T_a = –40°C to +85°C (wide-range specifications)
