Notes:
1. Referenced to AV_CC = V_CC1 = V_CC2 = V_REF = 3.0 to 5.5 V, V_SS = AV_SS = 0 V at T_opr = -20 to 85°C/-40 to 85°C
unless otherwise specified.
2. This applies when using one A/D converter, with the ADSTBY bit for the unused A/D converter set to 0 (A/D
operation stopped (standby)).
3. Use when AV_CC = V_CC1 = V_CC2.
4. Do not use A/D converter V_CC1 > V_CC2.
5. When analog input voltage is over reference voltage, the result of A/D conversion is 3FFh.

Notes:
1. Referenced to V_CC1 = AV_CC = V_REF = 3.0 to 5.5 V, V_SS = AV_SS = 0 V at T_opr = -20 to 85°C/-40 to 85°C unless
otherwise specified.
2. This applies when using one D/A converter, with the D/A register for the unused D/A converter set to 00h.
3. The current consumption of the A/D converter is not included. Also, the I_VREF of the D/A converter will flow even
if the ADSTBY bit in the ADCON1 register is 0 (A/D operation stopped (standby)).
