Default Group buy/Interest list - TDA1541A Core board.

Hello fellow diyers,

Please leave your name and number of boards required.

Eg:

"Ryanj x1" - then just copy and paste to add more names.

To bring you up to speed: Any good TDA1541A DAC kit?

Features:
-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.

Dimensions:
75mm x 60mm


Latest design:

Update 9/6/14:
Distinction-1541
Thanks to everyone that has shown an interest in the board now named "Distinction-1541"

Update 19/6/14:
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.
Update 9/7/17:
PCBs have been received!
-2oz/70μm copper
-Electroless nickel/immersion gold plating
-1.2mm thick for impedance matching
Distinction-1541 PCBs
