4-Channel, Sigma-Delta ADC Function Card

ProDAQ 3430

Features & Benefits

  • 4 simultaneous analog inputs
  • 16-bit resolution
  • Up to 1 MS/s/ch
  • Differential or single-ended input
  • Signals brought in range or zeroed with single-ended input
  • Front-end filtering (6-pole Bessel filter) to prevent ringing
  • Driver support for Windows, VxWorks, and Linux


The ProDAQ 3430 is a 4-channel, sigma-delta ADC function card. Every channel contains front-end conditioning circuitry followed by a sigma-delta ADC. The bit stream from every ADC is then directed to finite impulse response (FIR) decimation filters. Users can activate up to 10 stages of the FIR filters. The filtered data from the selected stages is then stored in the FIFO. The data from the FIFO easily can be moved on-the-fly to the motherboard or to the host.

Users can configure the ProDAQ 3430 to work independently or synchronize with other ProDAQ 3430 function cards. The multi-board synchronization requires that the same sampling clock and sync signals are distributed to all ProDAQ 3430 function cards.
