FPGA-based 64-Channel Analog Input Card Introduced

Concurrent Real-Time, a global provider of high-performance Linux solutions, today announced availability of model CP-ADS6418, a 64-channel, 18-bit, analog-to-digital converter card. The new card is designed for high-performance data acquisition and hardware-in-the-loop simulation applications. The card is also fully supported by Concurrent’s SIMulation Workbench real-time modeling environment.

The CP-ADS6418’s successive-approximation-register (SAR) design converts up to 500K samples/second per channel when using 64 channels. The card can also be used as a 32-channel card supporting up to 700K samples/second per channel. In addition, two channels can be combined to sample as a single channel providing up to 32 channels converting up to 1 mega sample/second per channel or 16 channels converting up to 1.4 mega samples/second per channel. Groups of 16 channels can be individually programmed by four independent clocks to collect samples at different frequencies.

The card is implemented using Analog Devices LTC2353 converters. Each converter group has an independently selectable clock source generated by a low-jitter clock generator. Overvoltage protection is included to prevent card damage. The card can be configured for single-ended input or differential input for low noise and accurate measurements. Multi-board clocking and synchronization is supported. A Concurrent RedHawk™ Linux® driver with an extensive software API that includes DMA and interrupt support is available.

“The CP-ADS6418 is a very cost-effective solution for applications that require large A/D channel counts and high-performance.” Says Ken Jackson, President and CEO of Concurrent Real-Time. “The card fully complies with the NIST traceable calibration standard.”
