Our PIANO DAC Shield has been designed for those seeking audio perfection. Every detail has been thought of!
First we start with 4 LDOs, one & two for the analog (avcc), the third for the digital (dvcc) and the fourth for the headphone amplifier.
Then we used film capacitors and thin film resistors in the audio path. All brand names (Vishay, SRcap, Stackpole...). Finally, our PCB has very good partitioning for digital and analog section.
If you understand all of the above, great! That means that you are an audiophile. If not, don’t worry… Just listen to the PIANO music!
PIANO houses a headphone amplifier based on the TPA6133A2 chipset and 3.5mm phone jack.
我們的PIANO DAC Shield專為尋求音頻完美的人而設計。每個細節都被想到了！
首先，我們從4個LDO開始，一個和兩個模擬（avcc），第三個數字（dvcc）和第四個耳機放大器。
然後我們在音頻路徑中使用了薄膜電容器和薄膜電阻。所有品牌名稱（Vishay，SRcap，Stackpole ...）。最後，我們的PCB具有非常好的數字和模擬部分劃分。
如果你明白以上所有，很棒！這意味著你是一個發燒友。如果沒有，別擔心，只要聽PIANO音樂！
PIANO安裝了基於TPA6133A2芯片組和3.5mm電話插孔的耳機放大器。
