Muses 72323 Buffer Board

[Nikon1975]

Dear All,

I produced few Muses72323 Input selector Buffer and volume control boards for my pre-ampifier. The board has four inputs, a DCB1 buffer and the Muses72323 volume control. One board has two channels. Low noise regulators on board.

I have an Arduino code to control the Chip.

Note: The boards have two little mistakes that can be easily fix when assembling them.

THIS IS NOT A BEGINNER PROJECT.

Price per board is 20 euros plus shipment. I have 8 leftover board.

Nice project, but please explain... why the buffer to drive the Muses and not to buffer the Muses output, which is far more important for this kind of attenuators I believe?

The buffer is in front of the volume control because in my preamp there is a gain stage after the volume control. I wanted the input impedance of the pre to be as high as possible and the output to be as low as possible.

What are the best libraries or examples to check out to write code to control the 72323?

 

[Nikon1975]

I can send you my libraries for Arduino. Not sure they are the best, but they work.

Do you have any boards left for sale ?

I can send you my libraries for Arduino. Not sure they are the best, but they work.

That would be very nice! You haven't put them on github?

 

[Nikon1975]

There are no more boards available, but I left the Arduino code in the first post, if you need to make your own.

Regards,
