The condition is that the error in a conversion started after tADC12ON is less than ±0.5 LSB. The reference and input signal are already
settled.

Approximately ten Tau (t) are needed to get an error of less than ±0.5 LSB:

(1)
The temperature sensor is provided by the REF module. Please refer to the REF module parametric, IREF+, regarding the current
consumption of the temperature sensor.
(2)
The temperature sensor offset can be as much as ±20°C. A single-point calibration is recommended in order to minimize the offset error
of the built-in temperature sensor. The TLV structure contains calibration values for 30°C ± 3°C and 85°C ± 3°C for each of the available
reference voltage levels. The sensor voltage can be computed as VSENSE = TCSENSOR * (Temperature,°C) + VSENSOR, where TCSENSOR
and VSENSOR can be computed from the calibration values for higher accuracy. See also the MSP430x5xx Family User's Guide
(SLAU208).
(3)
The typical equivalent impedance of the sensor is 51 k
. The sample time required includes the sensor-on time tSENSOR(on).
(4)
The on-time tVMID(on) is included in the sampling time tVMID(sample); no additional on time is needed.
