Product short description:
  • 16-bit DAC
  • 16 channels voltage output
  • Waveform memory
  • Extended temperature range
  • PCIe bus interface

The AP235 outputs analog voltage signals to drive up to 16 devices. When used with a carrier that holds two AcroPack AP modules, up to 32 voltage outputs can be obtained from a single card cage slot. The AP235 is ideal for waveform generation application that require high speed capabilities.

AP235: 16-bit DAC, 16 channels, analog voltage output module description

The AP235 outputs analog voltage signals to drive up to 16 devices. When used with a carrier that holds two AcroPack AP modules, up to 32 voltage outputs can be obtained from a single card cage slot. The AP235 is ideal for waveform generation application that require high speed capabilities.

Each output channel has its own 16-bit D/A converter (DAC). Individual DACs are faster, and they eliminate glitches typically caused by the re-acquisition process of sample and holds found on multiplexed output boards. A 64K sample memory is provided for waveform storage on board. This memory is shared between the sixteen channels. Waveforms can be continuously output from onboard memory without host intervention.  Additionally, a DMA controller is provided for streaming waveform data from host memory.

Designed for COTS applications these these analog output modules deliver high-density, high-reliability, and high-performance at a low cost.

AcroPack modules are RoHS compliant and ideal for military, defense, automation, aerospace, scientific, and development labs industries.

The AcroPack® product line updates our popular Industry Pack I/O modules with a PCIe interface format. This COTS tech-refresh offers a compact size and low-cost I/O in a rugged form factor. Combine different AcroPack modules on one carrier for a simplified modular approach to system assembly.

The AP235 modules are 70mm long, 19.05mm longer than the full length mini PCIe card. The board’s width is the same as mPCIe board and use the same mPCIe standard board hold down standoff and screw keep out areas.

A down-facing 100 pin Samtec connector will mate with the carrier card. Fifty of these signals are available as field I/O signals.
