This project is considered an upgrade to DAC1136, as the chip for DAC1136 is difficult to obtain. However, DAC1146 is relatively easy to purchase. I purchased 2 and they are very new. There are two versions of DAC1146. The first version has a plastic shell that is all black with silk screened white font. The internal R-2R part of this structure uses an AD7541 ceramic encapsulated gold cover plate. The second version is a plastic shell with white stickers, which uses ceramic packaging for the AD7541. Regardless of the structure, it can refresh you and his voice is very good. It is not something that IC can imitate. I like modules.Now share with everyone.You will get his PCB at a very low price. But he is in China.If you are a friend of the European Union. Please provide the IOSS number, which consists of IM and 10 digits. The mailing time is about 10 days. All PCBs consist of four parts: audio input board, format conversion board, DAC decoding board, and power board. You can play app content through a Bluetooth chip (purchased in China, manufactured in Shenzhen), or use CS8412 coaxial to play CD content. COMBO384 can also be used to connect to a computer for playback, and there is also an external input IIS interface for connecting to Philips turntable playback. I will provide Taobao product connections. You can use Taobao's overseas warehouse to purchase. If you need assembly instructions and BOM list, please send an email: 410746700@qq.com，My store address: hikvocal.taobao.com
