(5) Contribution only due to the reference and buffer including package. This does not include resistance due to PCB trace.
(6) 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)).
(7) The condition is that the error in a conversion started after t
REFON
is less than ±0.5 LSB. The settling time depends on the external
capacitive load when REFOUT = 1.
