Tables 20.9 and 20.10 list the A/D conversion characteristics.
Table 20.9 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, φ = 2 MHz to maximum operating frequency,
T_a = –20 to +75°C (General specifications), T_a = –40 to +85°C (Wide temperature
range specifications)
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, φ = 2 MHz to maximum operating frequency,
