An integrator with a maximum of flexibility can be made with an ADC and some timers/PWMs. Every parameter can be adjusted by programming, stored in EEProm, changed automatically or by pushbutton.... Everything is possible, you are in the world of PSoCs!!!
Check out AN2223. This shows how a naked op amp can be created using an SC block. Though this does not give you all the three terminals of the op amp on pins, maybe you could use this op amp for your application.
thanks ganesh and bob
i am going through the application note...
can you suggest me any application note which explains how to configure a switched capacitor block as an analog integrator. my prime need is that once started,this integrator should operate concurrently with other modules. it should not use CPU except at the time of initialisation.
What is the actual use of the OpAmp as integrator, filter, control loop ?
You need the NI pin for ?
I see I got sucked into posting on a 10 year old thread.
Dana, I can assure you the thread is "only" 10 MONTHS old. Nevertheless I would like to see that the forum-software even blocks Cypress-employees to reply to out-dated threads or at least have them informed of that fact.
Dana and Bob, my work is not limited to solve one particular person's problem. As you can see the thread was left unreplied to the user's specific question since 29th Feb 2012. My response was not only to address the thread creator's question, but was to address much larger audience who can benefit from this. For your information, the application note AN2041 was updated 2 quarters back to include information on quick settings required for different SC block applications.
By the way, I would have replied even if the thread was 10 years old.
my reply did not address you and your mission to supply us with worthy informations but this , well, crippled forum software that suffers from many shortcomings of which is the hint of posting to an old thread is one of the lesser ones.
Of course I did follow your link in the post (like all us top-contributors do) reveilling it was updated last october. When you compare the (old) header of the thread with the information you supplied us with, you can see what I mean: When someone is searching for information, he'll (or she'll) most likely not find your hint. I like to get informed about updated AppNotes if it is not too much to read for a day.
Another shortcoming of the forum software is that it crashes when I try to insert a smiley.
Rajiv, re-educating the planet that the earth is round on a periodic basis probably
not a productive use of anyones time. Especially yours, we need your expertise on
stuff going forward, clerical stuff no. Am I wrong ?
Your point "My response was not only to address the thread creator's question",
is the original poster really watching this ? I have my doubts.
And "address much larger audience who can benefit from this", look at the number
of views on your re-education posts, if they are meaningful, then why limit yourself
to 10 year old posts ? Why not start at the very beginning of the forums and reply
to everything. If #views not meaningful, then the value of your time has been lost.
As far as ap notes updated, Cypress has a very good URL link to its ap notes showing
by ascending date order revisions. I use that quite regularly. Why not at forum summary
page that shows highlighted link to that at top, therefore eliminating update threads in
the forum. After all too much info is equally as bad as too little. Maybe a video link as well.
Cypress forum is very important, not because somebody tells me an ap note has been
updated, or an old thread completed to your satisfaction, without the orginal posters
input per se. It is because the forum reveals problems many of us have not necessarily
tackled, shares the ones we have, and generally speaking is forward looking. Your method
may wind up responding to obsolete device threads, people dead threads, designs long
We need your expertise as an experienced EE, not as a cleric.
Professor, first of all, this is neither "10 YEAR" old thread nor the device is obsolete. The thread may be obsolete for the creator. But not for others.
I don't want to make this thread a boxing court. Leave this matter here. You have a different opinion than mine. No use in trying to find who is correct.
no one wants to make a boxing court out of this here!
But when the two top-contributors of ths forum are telling you that tey are not quite satisfied with the way you act here then a bit of insight would not be as bad.
You should consider who is to benefit from this forum. Cypress? Cypress's customers?? Or even both???
And I will not take advices like "Leave this matter here" when it is of interest for us or me.
If you do not want to discuss that openly you may always get my office-email address.
