SOLD
This is a I2S to simultaneous mode TDA1541 dac board designed by Miro. I have built a few boards, sold a couple of them and i am only keeping one board for my own system. This is last spare completed board i have to sell since i have completed my adventure, and keeping one set for myself in my system . It is built with care and high quality parts, tested to work with stability. Your own PSU and i2s source is required to complete this DAC for it to sing.
The 14 decoupling caps for the TDA1541 chip are WIMA MKP10. Decoupling caps for the psu are KEMET MKP, and electrolytics are mainly Nichicon FG for the DAC section and ELNA Bipolar for the op amp IV. Resistors used are Vishay, including the zero ohm jumpers and the IV resistors is DALE RN60. Logic chips are decoupled with high quality Kemet SMD x7r capacitors.
This dac is designed by Miro and more info can be found here :

Miro also designed the PSU for this dac (not included in this sale):

Please study the power supply requirement carefully if you intend to use your own psu design.
Important things to note :
1. If you intend to have no capacitor at the output, it is advisable to have a dc protection board as explained in the post:

2. Tested with JLSounds i2s card, i have trimmed the TDA1541 offsets to be null and very stable. Any changes to the board, including inserting different op amp and different TDA1541 chip will require adjustments again. Please do check and do necessary adjustments by following the instructions by Miro. You will need to explore this on your own, with your i2s source connected.
3. All components, including the TDA1541A and the OPA627 chip are new and needless to say genuine, which is only used for the testing of this DAC.
The whole board, with shipping worldwide included is priced at US$250. Members who bought and received my items know that i pack my items with utmost care to prevent possible damages. PayPal available.
