Dear We are a professional supplier of NTC temperature sensors, thermistors zinc oxide varistors and so on. Our product application includes surge current, temperature compensation, precision temperature sensor, and temperature control. We are supporting customers from QTA, low/medium volume to mass production and free sample. We have a professional team with more than 20 years of work experience in The Thermistors filed, also have passed plenty of approvals, such as ISO9001:2008, ISO 14001: 2004 ,GB/T29490,TUV, CQC, UL. Provide satisfied service and make sure customer's cost down is our vision. we shall be our customer's obvious choice when selecting the right partners for their NTC thermistors supply. Could you give me the contacts of your purchase department? Hope to hear from you soon.

The calculation of R1 is wrong, when I do addition inside the root, I got R1 as 55.346 ohm. but in TI's circuit note, the R1 calculation is multiplication inside the square root. That time R1 is same as in the video. the document link is given below www.ti.com/lit/an/sboa323/sboa323.pdf?ts=1613541925432&ref_url=https%253A%252F%252Fwww.google.com%252F
R1 = sqrt(2.252k x 819.7) = 1.359k
Where did the Vmid come from?
how do you get the formula for R1? what steps have you taken for R1 formula?
I didn't get the sqrt of NTC to calculate R1. What is the relationship?
Slight error in the calculation of R1. The value is correct but the equation should be the geometric mean but has an addition symbol instead.
Thanks for bringing this to our attention, Ron. We are working to get the equation updated in the video file.
@@TexasInstruments What is the correct equation?
@@mandytyree5028 R1 = Sqrt (RNTC@25C * RNTC@50C), i.e. instead of adding the two values, they should be multiplied.
Thank you so much.
sorry but what number of part are you using for NTC value ?
what would be of this mortal engineering student without the help of these kind of videos
how can we find the minimum detectable temperature difference in NTC thermistor sensor? appreciate it.
good question! or better yet how can we modify the min. max. temps to suite our own purposes. i.e. say 15C-35C
Many many Thanks
