We recommend the following alternative solutions:


High frequency DAC for demanding sonar application

  • High frequency generation allows for transmit pulses suitable for small targets
  • Board-board synchronization facilitates high channel count systems
  • Short form PCI Express™ form factor enables compact, lightweight solution

Designed to work together

The ICS-1620 has been designed to work seamlessly with the Abaco Systems ICS-1640 high speed analog to digital converter card which allows sonar system integrators to easily develop a fully synchronized transmit and receive application.

Compact and well suited for SWaP constrained environment

Short form factor PCI Express x4 card, making it extremely compact and well suited to size- and weight-constrained environments such as unmanned vehicles. The ICS-1620 features 16-channel, 2.5 MHz 16-bit resolution DAC capability, and offers a higher output signal bandwidth than can be achieved with boards using commercially available delta-sigma DACs.
