another bit lesson learned about sensor, great and excellent presentation sir randy. hoping another class session from your end with respect to instrumentation and controls...

thanks again and now, i am going to day 5 presentation of last day class of sir randy...thanks also to DIGIKEY and DESIGN NEWS...

with al the lesson gathered from your prresentation, giving me to familiar all those devices used...i am now on slide 20...nearing to the end of the presentation...

i am now on slide 18, great presentation sir randy...

i am now on slide 14 of the presentation...

i am now in slide 3 of this lesson...

i am in the field of building services engineering by profession in electro-mechanical engineering...

i just took my dinner and now go back again with the lesson of day 4 class...

just downloaded the slides presentation and gonna start with the lesson sir...

good evening sir randy, here i am again for another day 4 class of the week...

@Chuck - both EE and SE

Great to have access to the recorded sessions!

Iron

Missed the live lecture

Taking the class offline

Looks like I better spend some time on the Digi-Key web site this weekend.  Nice to see the devices you show and the range of products that are here today.  Glad for TI WeBench and DeV Kits!

Thanks Randy

I'm using 10 bit AD and would like more

Dont forget digital output types

 

Primarily I'm a software engineer but with a BS in mechanical and another one in electrical engineering

Looking forward to another informative lecture

Thank you Randy, very good session

That's going to do it for today. Until tomorrow, thanks for attending.

Thanks. Since I saw someboady add it.

Hi Randy,

My question is if I add a PI filter into analog signal channel between outbut buffer and ADC input for noise filter. It's a normally way, I am right?

If you have an extremely noisy situation it may provide a solution. In many cases it would not be required, so you need to verify that something additonal is necessary to solve a noise problem.

Good presentation, thanks

For someone who is new in this field, how can she/he discerne which features (in a datasheet) are essential and which are for gaining additional performance?

 
Sometimes a flyer for the IC provides a better features and benefits discussion. Alternatively, the press release for the IC or an article about the IC in a technical magazine may put the features in proper perspective. Ultimately, if you are meeting a design requirement specified by a customer, that may allow you to zero in on required vs nice to have features.

What about the TI web bench -- is the conditioning not part of that system?

Good point. For those that did not catch yesterday's session, TI Webbench provides signal conditioning for sepcifc sensors in their database and they have alternatives for the ICs in the design so you can zero in on the ocst-perfoemance tradeoff you need.

Iron

Do vendors have an app to guide the user in selecting the right IC for signal conditioning/conversion?

 
A few that I have seen show tables comparing the capabilities of their devices. In most cases, you satrt with the output type you are dealing with and then they show the ICs in that area.

Similar problem (had to keep rehitting "play" and periodic "refresh page").

Iron

I also experienced repeted cuts of the sound. Kept pushing play button to regain audio.

Iron

Just a comment for the WEB moderators - The audio on my computer keeps cutting out.  The player button keeps acting like the "Pause" button was pushed.  I can sometimes get it going just by hitting the "play" button on the audio control bar, but today was unusually bad.  I only got through about half of the slides.

I did try refreshing the screen several times but nothing seems to work.

Iron

Randy:

A good four days -- it has been a reminder to me about the range of sensors out there. You actually provided a solution to one long standing problem in an ore refining system we have,

Iron

Thank you guys and wonderful lecture.

Iron

Randy,

Have you ever used GPS for Macro positioning?

 

Unfortunately, I have not.

Thanks for the presentation.

Iron

Thank you for the today presentation.

Iron

Thanks for attending, everyone.

Blogger

Thanks guys... interesting parts and discussion

Iron

Same here sometimes I have to re-type my question/comment

Iron

Thank you Chuck & Randy

Iron

Thank you both, Randy and Chuck

Iron

Thank you Randy and Chuck.

Iron

Thanks Randy & Chuck

Iron

I had it few times in last year, I had to retype my question again

Randy, thank you for today's lecture

Iron

Thx Randy & Chuck.

Iron

Yes. Over the last few months about a dozen innocent comments got cut. Surprisingly the subversive comments went through. strange...

Iron

Conversion speed is sometimes an issue.

Iron

Usually there is a delay before the comment shows up, but it has always shown up eventually.

Iron

Yes at the beginning, now it seems ok

Iron

I have experienced that at times.

Iron

Is anyone having trouble with making comments?

Blogger

Oh, yes, we are definitely moderating comments.

Blogger

Disappearing comments here too...

Iron

Chuck I notice sometimes when I post comments they disappear.

 

Is someone moderating these comment submissions ?

Iron

can I plug in a PI fillter between the analog output pin and ADC input for decreaseing noise?

 

Iron

Depends on the application, but 16-bit can be sufficient.

Iron

we needed at least 1mV resolution on quantum sensors (with 0-400mV range) so 12Bit is about enough, but 14Bit would be much much better.

Iron

12-16 bits, depending on application and customer needs.

Iron

10 bit is enough for most of my designs but I needed a 20 bit in a past project.

Iron

Have used 24 bit but 16 bit is usually  enough.

Iron

There are tradeoffs.  It would depend on your app.

Iron

Always need more... but for current work 16 will work fine.

Iron

16 bits is usually more than we need.

Iron

mostly 16-bit is enough for our current applications

Iron

I am OK with 10 to 14-bit resolution.  We use 14-bit most of the time

Iron

12-14 bits is usally sufficient for the work I've done

Iron

99% of the time, 16 bits is adequate for us

Iron

yes, typically only use 12-bit

Iron

Good evening everyone.

Sherlock :Try reload page

Iron

reloading works for me too.

Iron

Yea I had to reload the page to for the audio to start.

Iron

CE, though I do a lot more electrical than software

Good afternoon everyone

Iron

Ok had to reload the page to get audio widget to work.

 

I am an EE in hardware and assembler programming

Iron

bartholemew - I had to reload the page several times for the audio to start.

Iron

Clicking the play button on audio widget does not start audio

I could download the Jan 24 and Jan 25 slides for this week.

I have been looking in the archives at the earlier sensors I lecture and cannot get the Jan 25th

Randy Frank lectuer from the archive as I find missing the "Slide Rule" icon to open the file.
