LM35: List of Test plans for qualifaction for LM35DMX/NOPB

Part Number: LM35
Other Parts Discussed in Thread: TMP117, TMP119

Tool/software:

Hi,

I want to use this part LM35DMX/NOPB (1C high voltage analog temperature sensor, 10 mV/C). But I am bit new on sensors. 

May I know the list of test plans required to qualify this sensor?

Regards

Kapil

    Hi Kapil,

    This will ultimately depend on your end application. In general, accuracy of the device should be tested to ensure proper operation. You would need a temperature reference for this--either testing the devices in a temperature controlled environment or using a device with higher accuracy for testing (something like TMP117 or TMP119). Analog temperature sensors will also be prone to parasitic capacitance or total capacitive load so some type of test could be run in the prototyping or manufacturing phase to ensure that the output is stable and not oscillating/ringing.

    Our devices are tested and calibrated in production and the specifications are ensured by our quality and manufacturing process so any testing that the end-user implements will be more of a system level performance (system accuracy, thermal response, etc.)

    Best regards,

    Hi Simon,

    Thanks for your valuable inputs. But again I would ask if TI has any application note for Temperature sensor functional test for reference.

    Hi Kapil,

    We do not have an app note like this available at this time. However, if you could share some document like this as reference from any other device, it would help me to give better guidance.

    Best regards,
