Condition A: V_CC = 2.7 V to 3.6 V, AV_CC = 2.7 V to 3.6 V, V_ref = 2.7 V to AV_CC, V_SS = AV_SS =
0 V, φ = 2 MHz to 20 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 3.6 V, AV_CC = 3.0 V to 3.6 V, V_ref = 3.0 V to AV_CC, V_SS = AV_SS =
0 V, φ = 2 MHz to 25 MHz, T_a = –20°C to 75°C (regular specifications),
T_a = –40°C to 85°C (wide-range specifications)
