FUNCTION AND VALUES
ADC Signal Source
Specifies the Signal Source of the Last User ADC Conversion. See Table 23 for the Definition of These
Signal Sources. Adc_src Reflects the Last Signal Source Converted. It Does Not Necessarily Hold the
Last Value Written to the ADC_src_sel Bit Field.
ADC Data Valid
Indicates That the Result in the Data Bit Field (Defined Below) Contains Newly Converted Data Since
the Last Time Adc_src_sel Was Written or This Register Was Read. Immediately After Power Up
Valid is False. Valid Becomes True as Soon as the First User ADC Conversion is Completed.
0: The ADC Result is Not a Valid Conversion of the Most Recently Selected ADC Source.
1: The ADC Has Finished Conversion and the Result is Valid.

FUNCTION AND VALUES
ADC Reading of the Internal (Die) Temperature (10-Bit Unsigned Integer)
This Bit Field Contains the Result of the Last Conversion of the LTC5100’s Internal Die Temperature.
The Scaling is 512 ° K or 239 ° C Full Scale, Corresponding to 0.5 ° C/LSB.
T = T_int_adc ? 0.5 ° C – 273 ° C, Where T is the Internal Temperature in Degrees Celsius.
