PT audio processor PCB.

PT Datasheet, PDF – Alldatasheet

I have no prior PCB designing experience and my electronics knowledge is basic. I have made a PCB with Fritzing and I would really appreciate it if you could help me with a “sanity check” of my design and component selection.

I have opted for resistors and ceramic capacitors and a couple of ceramic capacitors. This is mainly to be able to create an even more compact module but it means that I have left out the input surge protection resistors in the PT example. I hope the choices I have made does not degrade the audio quality noticeably and is still “safe” enough.

PT datasheet MS datasheet A couple of screen captures from the datasheet: I have also included a few photos of commercial implementations of the PT for reference: Some homemade uses of the PT Since this is a simple design, the board you have designed should work, but I would like to point out things that would save you from having troubles in more complicated designs.

From electrical point of view: For every power input pin of the IC especially digital IC’s you must place a bypass capacitor a capacitor from Vcc,Vdd, This capacitor is needed to filter out the noise coming from and going back to power supply rail. Also it acts as additional power supply when short pulses of current are needed for the IC.

Keep signal tracks as short as possible. Long tracks can pickup noise a lot easier. This might lead to noisy analog signal and even parasitic oscillations.

For this reason I would suggest placing components in different way. As in the pictures you have attached, all capacitors should be close to the pins of IC. Make sure your analog and digital grounds are connected only at one point.

Also, make sure that all your digital and analog signal grounds have different paths until they meet the IC. Otherwise you will have a digital noise in your analog circuitry, it can even cause parasitic oscillations.

You definitely don’t want that. Some additional guidelines for a good PCB design: Vias must be apart from component pads. There must be at least some solder mask between them. Otherwise when soldering in the oven, the solder will be sucked by via.

Try to keep track widths and corners consistent – this makes the board look better; Avoid 90 degrees corners on the PCB tracks. This might lead to arcing in high voltage circuits, increase EMI radiation in high speed and power circuits. They might lead to EMI problems.

Also it will affect the impedance of transmission lines.

Thanks for the great feedback VaidasZ! I’m currently implementing daatasheet of the changes you propose and will post updated daatasheet later. I finalized the updates and tried to implement as many of the suggestions as possible without total rerouting. Most of the audio paths are short, exept for the two audio channels that needs to cross the IC due to the IC’s pinout. The schematic is not my proudest moment I focused my attention on the PCB I’m experiencing some strange drawing bugs in Fritzing, some of them can be seen in the schematic file and on the IC labeling.

Luckily these are only minor problems. I bought a pair of 3w 4ohm USB speakers that I intend to gut and use.

Please let us know your experiences with these ICs. Hi, please can you put your code here.

I bought a Pt chip, I have build pt231 board but I can’t write the sketch. Thank you, Best regards. I built PCB using application circuit from datasheet.

I put PT on it with others elements. From GitHub download library PT Write some sketch with some instructions and send to Arduino volume,channel, etc. Audio does’nt go throu PT Does someone have some example of sketch?

Please share PT example arduino code.
