Help with LTC1298 and MAX1270 ADC

Hello,
I have been using a LTC1298 to read an analogue signal but I now wish
to read three analogue signals. I was thinking of using the MAX1270
found on the Parallax site but this is an 8 channel. Is there a 3 or
four channel one out there and programing diferences are there.
I am using a BS2e

Depending on how fast you need updates, do what I have done on
some of my industrial projects. Use an LTC1298 to convert two
channels at a time and use a stamp output to operate a DPDT relay to
switch between 4 inputs ( two at a time ). If you need to sample
quickly, use an analog switch chip ( 4066 ) to switch one of 4 inputs
into one channel on the 1298. If you need a sketch, email me directly.
