I already got two sample LTC1867s from Linear. It was the best I could find with 8 inputs, so that I would not have to use a separate switch. And only 16 pins, so it should not be too difficult to solder. The most I have done is 8 SMD pins.synaptech wrote:Order samples from Maxim. You should be able to get all you need for this project for free if you use an analog switch to mux the inputs.
I am interfacing them to a PIC18F2450 so that I can use it as a datalogger.
Now, where can I get free custom double-sided PCBs? I can't do toner transfer on the small SMD pads.
How did we get so off topic?
