Model AD8CH12-100DMA has eight simultaneous-sampling 12-bit A/D converters, and can continuously acquire and transfer hundreds of megabytes or even gigabytes of A/D data directly into host system memory at up to 100 MB/s, via 64 or 32 bit PCIbus DMA. It can acquire and transfer eight 8-bit A/D channels at up to 12.5 MSPS each (100MB/sec aggregate), or eight 12-bit A/D channels at up to 6.25 MSPS each, or four 8-bit channels at up to 25 MSPS each, or four 12-bit channels at up to 12.5 MSPS each.
