(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, as well as,
used as the reference for the conversion and utilizes the larger buffer. When REFOUT = 0, the reference is only used as the reference
for the conversion and utilizes the smaller buffer.
(2)
The internal reference current is supplied via terminal AVCC. 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 via terminal AVCC 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 PCB trace, etc.
(5)
Two decoupling capacitors, 10F and 100nF, should be connected to VREF to decouple the dynamic current required for an external
reference source if it is used for the ADC12_A. See also the MSP430x5xx Family User's Guide (SLAU208).
(6)
Calculated using the box method: (MAX(-40 to 85°C) – MIN(-40 to 85°C)) / MIN(-40 to 85°C)/(85°C – (–40°C)).
(7)
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.
