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 1024 data acquisition channels. If more channels are desired up to 16 units can be operated in parallel with the use of PhotoSound’s synchronization hub (LEGION Sync) leading to an unprecedented 4096 channels. Incoming analog signals can be amplified on each channel by a fixed 40 dB using optional, integrated preamplifiers. Upon special request, the linear probe is available without housing for the end-user to integrate custom photoacoustic arrays.
