mPCIe-ADIO16-8F PCI Express Mini Card Family with 8 Single-Ended or 4 Differential Analog Inputs, 4 Analog Outputs, 16 DIO

The mPCIe-ADIO16-8F is an ideal solution for adding high-speed analog I/O capabilities to any computer with an mPCIe slot.

The mPCIe-ADIO16-8F is a 16-bit resolution A/D & D/A board with 16 flexible digital I/O, with 8 single ended or 4 differential analog inputs. Each channel can be independently software configured to accept any input ranges.

Sixteen digital I/O configured in 9 “I/O Groups” as input or output per group. Bits 0-7 form one group, and bits 8-15 can be configured for input/output mode individually. The digital inputs implement various “alternate functions” including external trigger of ADC or DAC.

Four analog outputs with uni- and bipolar 5 and 10 volt ranges and a ±2.5V range round out the feature set.

The “FDS” model includes a new DMA-driven hardware-timed buffered DAC output feature, “DAC Waveform Streaming”. This feature allows one or more of the DACs to output voltage levels at a software-configurable rate as high as 1 million samples/second. Although the maximum rate is divided by the number of DACs being used, all DACs’ outputs update simultaneously on the hardware clock’s tick — all four DACs can output simultaneous data at 250 kilosamples/second, or one at 1 MHz! All the data is transfered by DMA to minimize CPU utilization, with IRQs so applications can send additional buffers of data as needed.

This tiny analog I/O board provides the user with everything needed to start acquiring and controlling signals in a variety of applications. The mPCIe-ADIO16-8F data acquisition board can be used in many current real-world applications such as embedded equipment monitoring, precision PC-based and portable environmental measurements, and mobile data acquisition. The board is designed to be used in rugged industrial environments and is double sided, mPCIe F1 sized.

Applications: Optical Networking, Instrumentation, Multichannel Data Acquisition and system monitoring, Automatic Test Equipment, Process Control and Industrial Automation, Power line monitoring.

Information about our Free Software packages:

ACCES is proud to provide a full suite of software support with every Data Acquisition product. We are committed to supporting the most popular operating systems and platforms for our customers. Currently we are actively supporting XP -> 10, both 32 & 64 bit, including “Server 2008,” “Embedded,” and “Compact” flavors for all plug-and-play products including PCI, PCI Express, USB, and more. Many products continue to ship with support for additional operating systems such as DOS, Windows 95, 98, Me, NT4, and 2000.


Among the software we deliver with our products are sample programs in a wide variety of programming languages. These samples are used to demonstrate the software interfaces to our products — and many can be used as-is in your production environments, or to test functionality of the devices out-of-the-box. We’re currently actively supporting sample programs in Microsoft Visual C#, Visual Basic, Delphi, and Visual C/C++, with many devices including samples in Borland C/C++ 3.1 for DOS. Additionally we provide National Instruments LabVIEW compatible DLLs and many demonstration VIs for our devices.


Drivers for various operating systems are also provided, including active support for Windows XP -> 10 — all in both 32-bit and 64-bit flavors, and including consumer, server, and embedded varieties — as well as the 2.6 and newer Linux kernels and recent OSX / macOS versions. Many products continue to ship with driver support for Windows 95, 98, Me, NT4, and Windows 2000, but support for these operating systems is considered deprecated.

Setup Programs and Utilites

Our Data Acquisition devices also include a graphical setup utility that walks you through the process of configuring any option jumpers or switches on the device, as well as explaining a little about the various connectors present.

Many devices also include utility programs – little tools to make your use of the device easier, such as EWriter, a program that allows you to read and write data in the user-accessible EEPROM locations on all our USB data acquisitition products; or WinRISC, a “Really Incredibly Simple Communications” terminal program that lets you get started instantly with serial devices.

“Register Level” Documentation

Besides all this software in all these languages and operating systems ACCES has a policy of open and transparent development: none of our lowest-level “register” interfaces are hidden from you — we document every register in every bus card, every command in every serial board, and every usb control transfer in every USB Data Acquisition board. These lowest-level interfaces allow you to develop for our products in ANY operating system or language, regardless of our actively supporting it or having a driver for it. We have customers actively developing in ADA, Android, Python, Java, MATLAB, Solaris, and more, just by referring to our complete low-level interface documentation! And we provide the full source code to all of our drivers, regardless of operating system, to give you an even bigger head start in your own development tasks.

No Fees or Royalties

All of this software is provided at no additional charge, and is licensed under any of a variety of flexible — and royalty free — options. Check out our software license explanation if you’d like more information.

Custom Software

ACCES also offers Custom Software Services for our products. Our prices are unbelievably low, often as inexpensive as free! If you need something tweaked to support your needs, or an entire enterprise application developed from scratch, it is definitely worth your time to inquire with us, first.
