NOTES:
1. Conditions: V_REF+ = 4.99712V, V_REF– = 0V. AI_CC value does not include the resistor ladder current. For the 40-pin package, where the
V_REF– inputs are connected to AV_CC and AV_SS, the current AI_CC will be increased by the register ladder current and may exceed the
maximum shown here.
2. The resistor ladder network is not disconnected in the power-down or idle modes. Thus to conserve power, the user must remove AV_CC and
V_REF+.
3. If the A/D function is not required, or if the A/D function is only needed periodically, AV_CC can be removed without affecting the operation of
the digital circuitry. Contents of ADCON and ADAT are not guaranteed to be valid. Digital inputs P1.0 to P1.7 will not function normally. No
digital outputs are present on these pins.
4. For this test, the Analog inputs must be at the supplies (either V_DD or V_SS).
