TMP006 field of view

Other Parts Discussed in Thread: TMP006

Can the TMP006 be used to sense temperature of small semiconductors (ex SOT-23) if at a close distance? What optical lens would be required if any?

    Hello Marcello,

    Yes, the TMP006 can be used to measure the temperature of small ICs at a close distance, but keep in mind that the optimal distance of the TMP006 from the object to be measured is d < (r/2) where r is the radius of the object. In the case of a SOT-23, this distance would be quite short and not feasible to implement, so the wide field of view of the TMP006 would integrate the temperature of the nearby area as well. Please refer to the TMP006 User's Guide (http://focus.ti.com/lit/ug/sbou107/sbou107.pdf) for more information.

    You can mitigate this by placing the TMP006 such that the angle of incidence from the TMP006 to the object is 0°, or directly in front. If I understand your intended application correctly, I would not recommend a lens in your case since it would optically amplify the IR energy from wider incident angles. What would work better is a cover made of a material with low IR emissivity (most polished metals will work, see Table 1 of the TMP006 User's Guide) with a small hole/aperture in the center that would restrict the ability of the TMP006's sensor from detecting IR other than what was being radiated from directly in front of it.

    Hello

    What is the time conversion of the TMP006 or a min time response?

    I need  5-10ms

    With best regards,

    Hello Anatoly,

    The IR sensor's response time is 17ms. The internal ADC has a minimum measurement time of 250ms which sets the data rate. Since the ADC is an integrating converter, thermal response as fast as 17ms will be captured.

    For future reference, please post new questions to a new thread instead of replying to an existing thread. This allows us to provide a quicker, better response to you.
