 hi to all,

              what is way to feed sine wave of  2.5v P-P to psoc 3. can we clamp the signal before giving it to board externally, or in the board itself is there any provision.

Thanks

PRP

 Use an external resistor & a capacitor and provide a bias of Vdda/2 using Vref component buffered by an OpAmp in buffer mode.

 

Refer to http://www.cypress.com/?rID=50815&cache=0 blog post.

 

Regards,

Kishore.

 Also make sure that your DVK is configured for 5V supply voltage instead of 3.3V.

Have a look at Dana's post in this thread http://www.cypress.com/?app=forum&id=2232&rID=66386

The methods used to translate a signal each have positive and negative

impact on design, in terms of accuracy, repeatability, cost, performance.

So most important is to state electrical goals first, then use those to qualify

solutions.
