4-8 Channel ADC for Altera DE2-115 using Simultaneous Sampling

I have used the LTC1407A-1 from Linear Tech and interfaced it to Cyclone III and Cyclone IV many times on various boards I've designed over the years. They also make a LTC1407A, which is a unipolar part, while the LTC1407A-1 is a bipolar type part.

You just need SCLK, CONV, and SDO for each ADC. Each ADC Simultaneously samples two channels at 1.5 MSPS.

This is an excellent part, I have had good experience with it.

I'd be happy to help you with the VHDL driver.:)
