Analog Devices is sure slow in releasing products.  I have a 94' data book
that describes the SSM2161 audio volume control.  I wanted to use this in
my design because I could easily attach a PIC through the 4-bit port A on
the 16C55.  They were supposed to come out with this part two months ago.

I need to find a part to substitute for the SSM2161.  It's basically a 4
channel volume control with a serial interface for transfering the volume
level to the part through a serial port.  The whole control system is
digital, so it would be ideal to keep the volume control digital also.

Does anyone know of a part that I could use to substitute in for this
one...Or better yet, a way to get a hold of pre-release samples of this
part.

Thanks,
