PT2314-D Datasheet

From Pt2341 download library PT Otherwise you will have a digital noise in your analog circuitry, it can even cause parasitic oscillations.

PT audio processor PCB.

Please share PT example arduino code. From electrical point of view: Long tracks can pickup noise a lot easier. Also it will affect the impedance of transmission lines. Also, make dayasheet that all your digital ddatasheet analog signal grounds have different paths until they meet the IC. This might lead to arcing in high voltage circuits, increase EMI radiation in high speed and power circuits.


Hi, please can you put your code here. As in datashete pictures you have attached, all capacitors should be close to the pins of IC. Otherwise when soldering in the oven, the solder will be sucked by via. The schematic is not my proudest moment I focused my attention on the PCB I put PT on it with others elements.

I built PCB using application circuit from datasheet. This datawheet is needed to filter out the noise coming from and going back to power supply rail. I’m currently implementing several of the changes you propose and will post updated files later.

I have opted for resistors and ceramic capacitors and a couple of ceramic capacitors. Luckily these are only minor problems.

Some homemade uses of the PT They might lead to EMI problems. 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 datashwet corners on the PCB tracks. Also it acts as additional power supply when short pulses of current are needed for the IC. This is mainly to be ph2314 to create an even more compact module but it means that I have left out the input surge protection resistors in the PT example.


This might lead to noisy analog signal and even parasitic oscillations. Thank you, Best regards. Write some sketch with some instructions and send to Arduino volume,channel, etc.

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. Keep signal tracks as short as possible. Pt234 definitely don’t want that. PT datasheet MS datasheet A couple of screen captures from the datasheet: Thanks for the great feedback VaidasZ!

Does someone have some example of sketch?

There must be at least some solder mask between them. Vias must be apart from component pads.
