Hi all, I'm designing a multi channel volume contol for my 7.1 Power amp. Hoping to use the:
CS3318: http://pdf1.alldatasheet.com/datasheet-pdf/view/167484/CIRRUS/CS3318.html
As master control.
MAX5440: http://datasheets.maxim-ic.com/en/ds/MAX5440.pdf
As balance and indavidual(per 2 channel) volume control.
contolled all with rotary encoders.
Firstly, anyone had any experence with these devices? How do they sound?
Can the CS3318 work well as a preamp? Or do i have to have a seperate stage?
I havnt got a clue on programing a microcontroller to recive grey code and send I2C to the CS3318. Can any one give an example code? I can work with C as i have little knowledge on it and I'm currently learning it. I have a PIC development enviroment and a programmer so i can have a try.
I'll post a block diagram of my idea when I get my scanner installed.
Thanks =].

No need to use two chips, the CS3318 can set each channel individually so one chip can do level, individual level offset, balance etc. It's just a matter of setting the individual channels.
On my website you see an example of how this *could* be done. I'm using the SPI interface, but that's not significant.
Audio quality is superb (that's what others tell me too).

If your PIC has the I2C accessory, using it is pretty straightforward. There's an I2C tutorial here: http://www.winpicprog.co.uk/pic_tutorial.htm
