LMT70: Typical & Maximum Accuracy

Carlo
Expert 7715 points
Part Number: LMT70

Hi E2E,

Good day.

Our customer would like to know the following details:

1. Can you explain typical vs. max accuracy? Is it part by part variation, or is it variation over multiple trials with the same part?

2. What sample size was used to determine these numbers? Does the typical represent an average of the trails? 

3. For matched performance the max is 0.1 °C   but what is a typical performance with max for the 30-40 °C range? For our application, we want to get as accurate as possible between the 30-40 °C range.  How do we ensure the typical performance of 0.05 °C?  Do we need to utilize a matched setup?

4. Will any 12 bit ADC work? For example, www.ti.com/.../ADC12010 Or the 12 bit ADC in the Arduino Due?

    Hi Carlo,

    Our max spec is the most deviation you can expect for the accuracy. This would be over part by part variation. The typical is the average. 

    For the given temperature range of 30-40 °C please refer to Figure 3 in the datasheet which shows the Min and Max limits across temperature.

    Any 12 bit ADC should have the resolution required for the slope of the LMT70 device.
