LM95071: Graph for Conversion Time vs Temperature

Sadanori Kato

Part Number: LM95071

Hi,

The graph for "conversion time vs temperature" is mentioned in LM95071 data sheet, so could you please tell me how the conversion time is measured ?
For example, they are the sample number per each temperature, the serial clock period, the process condition and so on.
In addition, could you please provide that graph in the worst case(the conversion time is 228ms.) ?

Best regards,
Kato

Hi Kato-san,

You can measure conversion time if you monitor current consumption with an oscilloscope. The current consumption will go down when the conversion ends.

228ms is the specification for worst-case conversion time across temperature, supply and process variation. We don't have additional charts to share.

Thanks,
Ren

Hi Ren-san,

Thank you for the explanation.

For figure 8, is this plot data measured with an oscilloscope ?
if this plot data is obtained by another method, please tell me how to obtain.

Best regards,
Kato

Hi Kato-san,

Monitoring the current consumption is one way to measure the conversion time. We typically use hidden features to speed up production test times and improve test coverage. I can't share details of hidden features or production test.

Thanks,
Ren
