Legion ADC

256-Channel Analog-to-Digital Converter

The LEGION ADC unit offers fully parallel operation for simultaneous data acquisition from all channels without multiplexing in an ultra-compact external USB enclosure. Each unit supports 128- and 256-element detectors. Up to four ADC units can be operated in parallel to enable an unprecedented 1024 data acquisition channels. Incoming analog signals can be amplified on each channel by a fixed 40 dB using optional, integrated preamplifiers.
