 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

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

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

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.
