BIT

(BIN)

FUNCTION AND VALUES

.Reserved

.Adc_src

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.

.Reserved

.Valid

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.

.Data

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.

.T_int_adc

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.
