有没有人知道是否有替代AK4201放大器在24位立体声DAC线路输出/耳机放大器子板（P/N:AC3200 32-2）？为什么微芯片会很难找到并获得芯片？
以上来自于百度翻译 以下为原文 Does anybody know if there is replacement for AK4201 amplifier used in the 24-bit stereo DAC Line-out/Headphone Amplifier Daughter Board (P/N: AC320032-2)? Why does microchip put chips that are difficult to find and obtain?

谢谢吉姆，我试过其他分销商，但我很难获得。你能建议一些其他IC能胜任这项工作吗？
以上来自于百度翻译 以下为原文 thanks jim, i tried the other distributors but difficult to obtain for me. Could you suggest some other IC that will do the job? |

它是一个原型构建，所以我想取决于我是否得到了工作，但放大器我会订购了两个，只是为了一个损坏。
以上来自于百度翻译 以下为原文 its a prototype build, so i guess depends on the whether i get the things working, but the amplifier i would have ordered two of them, just in case one damages. |

嗨，不，我没有要求样品，我还没有能够为我的地区挑选合适的经销商。类似地，AK438 4VT（DAC）也从我的分销商失去了库存。现在我正在寻找替代的DAC /放大器电路的立体声？但是在PIC蓝牙参考指南中没有找到这个要求。我的意思是什么DAC /放大器规范我应该选择W.R.T.PIC32 MX MCU？我认为SPI或I2C接口是使用的，但模拟规范我怎么知道？
以上来自于百度翻译 以下为原文 hi, no i haven't asked for sample, i haven't been able to pick up the right distributor for my region. similarly AK4384VT(DAC) is also out of stock from my distributor. Now I am looking for alternative DAC/amplifier circuit for the stereo? but the requirement is not found in the PIC bluetooth reference guide. I mean what DAC/amplifier specification should I choose w.r.t. PIC32MX MCU? I think SPI or I2C interface is utilized but analog specification how can I know? |

我位于南洋，我的经销商在泰国。它大部分都像DigiKy。是的，这是我的爱好，我想建立，也因此，投影仪知道一个类似的立体声电路与外部DAC和放大器耳机。部分也是可用的，但我不知道如何/什么检查，使电路将与PIC32 MX合作？有没有帮助正确的方向？
以上来自于百度翻译 以下为原文 i am located in southeast asia, and my distributor is in Thailand. It has most part and is like digikey. yes it is my hobby which i want to build and also/hence a project i know a similar stereo circuit with external DAC and amplifier for headset. the part are also available but i am not sure how/what to check so that the circuit will cowork with the PIC32MX? any help into right direction? |

如果你无法说服经销商向你取样，我会使用“AC3200 32-2”。
以上来自于百度翻译 以下为原文 If you are not able to convince the distributor to sample you the parts I would use the "AC320032-2" |

谢谢吉姆，你知道PIC32 MX微控制器的音频幅度吗？有没有一种方法可以从数据表或者其他的笔记中知道？或者是DAC和AMP到底需要什么？
以上来自于百度翻译 以下为原文 thanks jim, would you know the audio amplitude level from the PIC32MX microcontroller? is there a way to know from datasheet or something for example any notes? or is DAC and amp actually needed at all? |

你没有共享一个示意图。PIC32 MX不直接输出模拟音频。
以上来自于百度翻译 以下为原文 You have not shared a schematic. The PIC32MX does not output analog audio directly. |

您好，DAC/AMP的示意图与PIC32连接。也许很难看清。请参考指南PDF:http://WW1.Microchip .com……EVICEDOC/7000 05140C.PDF.同时Google替换AK4201我得到了这个TPA6139A2AMP。但它的额定功率只有25兆瓦，使用3.3V的32欧姆。你认为这个安培会代替我的情况吗？谢谢
以上来自于百度翻译 以下为原文 hi, the schematic of DAC/amp is shown with connection to PIC32. maybe difficult to see. please refer to the guide pdf: http://ww1.microchip.com/...eviceDoc/70005140C.pdf also while googling replacement of AK4201 I got this TPA6139A2 amp. But it is rated 25mW only for 32ohm using 3.3V. Do you think this amp will work as replacement in my case? thanks Attached Image(s) |

从图中可以看出，PIC32 MX输出逻辑电平串行数据。你到底在想什么？
以上来自于百度翻译 以下为原文 As you can see from the schematic the PIC32MX outputs logic level serial data. What exactly are you thinking of making ? |

我想把PIC32 MX单片机的音频发送到耳机连接的3.5mm立体插座。PIC32通过USB接收来自计算机的音频，并将其发送到耳机/耳机连接的3.5mm插座。但是你认为TPA6139A2AMP能做耳机的工作吗？更换AK4201放大器？
以上来自于百度翻译 以下为原文 I want to send audio from PIC32MX MCU to the 3.5mm stereo socket to which headset will be connected. The PIC32 receives audio from computer via USB and sends the same to the 3.5mm socket to which headphone/headset is connected. about the amplitude level i understood now. but do you think the TPA6139A2 amp will do the job for headsets?replacing the AK4201 amp? |
