Not guaranteed by production test but by design and/or characterization data at production release.
Valid for current ADC gain setting of PGA up to 64.
These numbers include temperature drift.
The offset error drift is included in the offset error. This typical specification is an indicator of the offset error due to temperature drift. This typical value is the mean of
the temperature drift characterization data distribution.
Includes internal reference temperature drift.
User system calibration removes this error at a given temperature and at a given gain on the current channel.
The gain drift is included in the total gain error. This typical specification is an indicator of the gain error due to temperature drift. This typical value is the mean of the
temperature drift characterization data distribution.
Voltage channel specifications include resistive attenuator input stage.
RMS noise is referred to voltage attenuator input; for example, at f
Valid after an initial self calibration.
It is possible to extend the ADC input range by up to 10% by modifying the factory set value of the gain calibration register or using system calibration. This approach
In ADC low power mode, the input range is fixed at ±2.34375 mV.
Valid for a differential input less than 10 mV.
The absolute value of the voltage of VTEMP and GND_SW must be 100mV minimum, for accurate operation of the T-ADC.
Measured using box method.
The long-term stability specification is noncumulative. The drift in subsequent 1000 hour periods is significantly lower than in the first 1000 hour period.
Die temperature.
Endurance is qualified to 10,000 cycles, as per JEDEC Std. 22 Method A117 and measured at −40°C, +25°C, and +125°C. Typical endurance at 25°C is 170,000 cycles.
Retention lifetime equivalent at junction temperature (T
These numbers are not production tested but are supported by LIN compliance testing.
Thermal impedance can be used to calculate the thermal gradient from ambient to die temperature.
