(AN7 to AN0 Input: 134/266-State Conversion)
Condition A: V_CC = 5.0 V ±10%, AV_CC = 5.0 V ±10%, V_SS = AV_SS = 0 V, φ = 2 MHz to maximum
operating frequency, T_a = –20 to +75°C (regular specifications),
T_a = –40 to +85°C (wide-range specifications)
Condition B: V_CC = 4.0 V to 5.5 V, AV_CC = 4.0 V to 5.5 V, V_SS = AV_SS = 0 V, φ = 2 MHz to
maximum operating frequency, T_a = –20 to +75°C (regular specifications),
T_a = –40 to +85°C (wide-range specifications)
Condition C: V_CC = 2.7 V to 3.6 V, AV_CC = 2.7 V to 3.6 V, V_SS = AV_SS = 0 V, φ = 2 MHz to
maximum operating frequency, T_a = –20 to +75°C

Notes: 1. When conversion time ≥ 11. 17 µs (CKS = 1 and φ ≤ 12 MHz, or CKS = 0)
2. When conversion time < 11. 17 µs (CKS = 1 and φ > 12 MHz)
3. In single mode and φ = maximum operating frequency.
