Acromag has announced an addition to their PCIe-based AcroPack Series. The AP225 offers a 12-bit D/A converter and the AP235 features a 16-bit D/A converter voltage waveform output model. These mPCIe (Mini PCI Express) based boards provide output signals to drive up to 16 devices. Each output channel has its own 12 or 16-bit digital-to-analog converter (DAC). The benefit of individual DACs is they 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 shared between the sixteen channels for waveform storage on board. A down-facing plug-in 100 pin connector ensures a secure connection for the I/O without any cabling. These modules plug into AcroPack PCIe, VPX, and XMC carriers in any combination for embedded applications running on Linux, Windows, or VxWorks operating systems. AcroPack AP225 and AP235 modules start at less than $1,100 and carriers at $750.

For easy integration of the AcroPack modules with real-time software application programs, Acromag offers C libraries for Windows, Linux and VxWorks systems. The libraries provide generic routines (source code included) to handle reads, writes, interrupts, and other functions. Demonstration programs enable the developer to quickly exercise the I/O modules before attaching the routines to the application program. This diagnostic tool can save hours of troubleshooting and debugging.

“We are pleased to add the AP225 and AP235 modules to the product platform,” stated Russell Nieves, Acromag’s Vice President of Sales. “Continued expansion of offerings is critical to providing the capabilities our customers require to meet the latest technological challenges and we at Acromag are committed to providing them with the best solutions possible.”

This COTS line of AcroPacks are SWaP-C optimized, RoHS compliant and ideal for scientific development labs, military and aerospace applications, the defense industry and automation applications.
