Compact, High Sampling and High Frame Rate Data Acquisition Unit with 32-Channel Analog-to-Digital Converter (ADC) and Integrated Preamplifiers

The FLASH series cover preamplifier, analog-to-digital converter (ADC) and complete data acquisition (DAQ) units with high channel frame and sampling rates optimized for photoacoustic microscopy and scanning applications as the highest priority. Key highlights include fully parallel operation for simultaneous data acquisition from all channels without multiplexing and compact size. Standalone preamplifiers are ideal for integration with third party ADCs or testing for optimal probe input impedances. Industry standard SMA connectors are connected to individual channels on all products for full connectivity control.


  • Compact housing and SMA for easy instrument integration
  • Very fast data transmission with up to 6000 fps or 100,000 data points per frame per channel
  • Data streaming in limited by USB3 data bandwidth. Higher data rates or bursts can be buffered using 1GB DDR memory buffer.
  • Integrated amplifier chips with digitally controlled gain
  • +40 dB Gain from compact 2 x 25 mm preamps per channel
  • Optical and electrical trigger inputs
  • Open SDK and access to raw data provided by DAQ software

Technical Specifications



The main feature of the LEGION series is the very high number of channels included in each product. High Channel Count (HCC) electronics are useful for high level parallel data acquision. PhotoSound’s number one goal is to design and optimize products for the photoacoustic imaging scientific community, however there are a number of applications that can benefit from multi‐channel data acquisition.

Exapmles of applications include but are not limited to:

  • Photoacoustic imaging
  • X-Ray acoustics
  • Other radiation source acoustics
  • 3D tomography
  • 2D imaging
  • Safety testing of manufactured goods
