I'm really new to any circuitry and electrical stuff... just got started with Arduino this week. I'm reading a datasheet for a temp sensor and can't understand all of the variables.
http://www.analog.com/media/en/technical-documentation/data-sheets/TMP35_36_37.pdf
This sheet on page three in the test conditions/comments section repeatedly refers to \$ T_A \$. What is that, temperature average or something?
I've scoured around but it's a pretty specific thing to search for. Does anyone know the best way to learn about these types of variables/abbreviations, or is it just expected that you're going to figure it out and know what this stuff means? I know datasheets are written for engineers by engineers but that makes a high bar for entry for those of us without the necessary tribal knowledge.
There are other things in there too -- \$ I_l \$, \$ V_s \$, etc. While I understand the primary variable the subset throws me off. I imagine there are a set of basic ones that I just need to learn...
