Tables 28.27 and 28.28 list the A/D conversion characteristics.
Table 28.27 A/D Conversion Characteristics (AN7 to AN0 Input: 134/266-State Conversion)
Condition A:
V_CC = 5.0 V ± 10%, AV_CC = 5.0 V ± 10%, AV_ref = 4.5 V to AV_CC,
V_SS = AV_SS = 0 V, ø = 2 MHz to maximum operating frequency,
T_a = –20 to +75°C (normal specification product), T_a = –40 to +85°C (wide
range temperature specification product)
Condition B:
V_CC = 4.0 V to 5.5 V, AV_CC = 4.0 V to 5.5 V, AV_ref = 4.0 V to AV_CC,
V_SS = AV_SS = 0 V, ø = 2 MHz to maximum operating frequency,
T_a = –20 to +75°C (normal specification product), T_a = –40 to +85°C (wide
range temperature specification product)
Condition C:

Notes: 1. When conversion time ≥ 11.17 µs (CKS = 0, or ø ≤ 12 MHz at CKS = 1)
2. When conversion time < 11.17 µs (ø > 12 MHz at CKS = 1)
3. At the maximum operating frequency in single mode.
