Group buy/Interest list - TDA1541A Core board.
Hello fellow diyers,
Please leave your name and number of boards required.
"Ryanj x1" - then just copy and paste to add more names.
To bring you up to speed: Any good TDA1541A DAC kit?
-Great for those wanting to experiment with different combinations of power supplies, output stages, dem circuits.
-U.FL I2s input for easy input from FIFO or the like, whether in time multiplexed mode or simultaneous mode. [pin 27 left floating]
-Add your own power supplies
-Add your own output stage
-Bypass cap pads on AOL and AOR to prevent RF from entering output stage. [47nf - depending on output impedance]
-Vias for DEM pins to add your own circuit.

Thanks to everyone that has shown an interest in the board now named "Distinction-1541"
I've ordered the boards. At the moment it looks like about a 3 week wait to receive them. Shortly I will invoice the members on the list. It will look something like this.
PCBs have been received!
-Electroless nickel/immersion gold plating
-1.2mm thick for impedance matching
