(1) The reference is supplied to the ADC by the REF module and is buffered locally inside the ADC. The ADC uses two internal buffers, one smaller and one larger for driving the VREF+ terminal. When REFOUT = 1, the reference is available at the VREF+ terminal and is used as the reference for the conversion and uses the larger buffer. When REFOUT = 0, the reference is only used as the reference for the conversion and uses the smaller buffer.
(2) The internal reference current is supplied from the AVCC terminal. Consumption is independent of the ADC12ON control bit, unless a conversion is active. REFOUT = 0 represents the current contribution of the smaller buffer. REFOUT = 1 represents the current contribution of the larger buffer without external load.
(3) The temperature sensor is provided by the REF module. Its current is supplied from the AVCC terminal and is equivalent to IREF+ with REFON = 1 and REFOUT = 0.
(4) Contribution only due to the reference and buffer including package. This does not include resistance due to the PCB traces or other application factors.
(5) Calculated using the box method: (MAX(–40°C to 85°C) – MIN(–40°C to 85°C)) / MIN(–40°C to 85°C)/(85°C – (–40°C)).
(6) The condition is that the error in a conversion started after tREFON is less than ±0.5 LSB. The settling time depends on the external capacitive load when REFOUT = 1.
