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.
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.
ADC Data (10-Bit Unsigned Integer)
Contains the Result of the Last User ADC Conversion. See Table 23 for the Definition of the Available
Signal Sources.
