Acromag has expanded its PCIe-based AcroPack® Series with the addition of the AP225 and AP235 modules. 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 that 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.

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