Thank you, Best regards. This might lead to noisy analog signal and even parasitic oscillations.

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 finalized the updates and tried to implement as many of the suggestions as possible without total rerouting. Keep signal tracks as short as dxtasheet.

Luckily these are only minor problems.

PT2314-D Datasheet

I built PCB using application circuit from datasheet. 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, I have no prior PCB designing experience and my electronics knowledge is basic.

Also it acts as additional power supply when short pulses of current are needed for the IC. For this reason I would suggest placing components in different way. Try to keep track widths and corners consistent – this makes the board look better; Avoid 90 degrees corners on the PCB tracks. Does someone have some example of sketch?

I put PT on it with others elements. As in the pictures you have attached, all capacitors should be close to the pins of IC.

Audio does’nt ;t2314 throu PT Otherwise you will have a digital noise in your analog circuitry, it can even cause parasitic oscillations. 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. Otherwise when soldering in the oven, the solder will be sucked by via.

Some additional guidelines for a good PCB design: PT audio processor PCB. PT datasheet MS datasheet A couple of screen captures from the datasheet: There must be at least some solder mask between them.

I bought a pair of 3w 4ohm USB speakers that I intend to gut and use. 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 dataheet complicated designs.

I bought a Pt chip, I have build the board but I can’t write the sketch. Also it will affect the impedance of transmission lines. I’m experiencing some strange drawing bugs in Fritzing, some of them can be seen in the schematic file and on the IC labeling.


Hi, please can you put your code here. I’m currently datashewt several of the changes you propose and will post updated files later. I hope the choices I have made does not degrade the audio quality noticeably and is still “safe” enough. I have also included a few photos of commercial implementations of the PT for reference: The schematic is not my proudest moment I focused my attention on the PCB From GitHub download library PT They might lead to EMI problems.

Some homemade uses of the PT I have made a PCB with Fritzing xatasheet I would really appreciate it if you could help me with a “sanity check” of my design and component selection. Long tracks can pickup noise a lot easier. Vias must be apart from component pads. This capacitor is needed to filter out the noise coming from and going back to power supply rail.
