10 Pcs Pt2314l Sop-28 PT2314 SMD Channel Input Audio Processor
Otherwise when soldering in the oven, the solder will be ptt2314 by via. I have also included a few photos of commercial implementations of the PT for reference: From GitHub download library 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.
Thanks for the great feedback VaidasZ! Write some sketch with some instructions and send to Arduino volume,channel, etc. I’m experiencing some strange drawing bugs in Fritzing, some of them can be seen in the schematic file and on the IC ;t2314.
They might lead to EMI problems. Also it will affect the impedance of transmission lines. I bought a Pt chip, I have build the pf2314 but I can’t write the sketch. Please share PT example arduino code. I hope the choices I have made does not degrade the audio quality noticeably and is still “safe” enough. I built PCB using application circuit from datasheet. Audio does’nt go throu PT I have opted for resistors and ceramic capacitors and a couple of ceramic capacitors.
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.

I put PT on it with others elements. From electrical point of view: This might lead to arcing in high voltage circuits, increase EMI radiation in high speed and power circuits.
For every power input pin of the IC especially digital IC’s you must place a bypass capacitor a capacitor from Vcc,Vdd, As in the pictures you have attached, all capacitors should be close to the pins of IC.
Vias must be apart from component pads. Long tracks can pickup noise a lot easier. PT datasheet MS datasheet A couple of screen captures from the datasheet: For this reason I would suggest placing components in different way.
There must be at least some solder mask between them. 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. I bought a pair of 3w 4ohm USB speakers that I intend to gut and use.
PT audio processor PCB
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. Does someone have some example of sketch?
Hi, pt314 can you put your code here. Keep signal tracks as short as possible. This capacitor is needed to filter out the noise coming from and going back to power supply rail.
Luckily these are only minor ph2314. PT audio processor PCB. You definitely don’t want that. The schematic is not my proudest moment I focused my attention on the PCB
