Product short description:
  • 12-bit DAC
  • 16 channels voltage outputs
  • Wide temperature range
  • PCIe bus interface

The AP225 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 AP225 is ideal for waveform generation application that require high speed capabilities.

[DISPLAY_ULTIMATE_PLUS]

The AP225 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 AP225 is ideal for waveform generation application that require high speed capabilities.

Each output channel has its own 12-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.

The AP225 supports 6 independent software selectable output ranges plus capabilities to monitor the status of each output.

Designed for COTS applications 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, low-cost I/O, the same functionality and memory map of the existing Industry Pack modules in a rugged form factor. Combine different AcroPack modules on one carrier for a simplified modular approach to system assembly.

The AP225 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 uses the same mPCIe standard board hold down standoffs 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.
