The USB-AI16-2A is a high-speed USB 2.0 device designed for many applications including laboratory and semiconductor fab signal analysis. This product is a USB-based Analog to Digital (A/D) converter board that features two single-ended 16-bit analog inputs with software selectable input ranges, per channel. The board samples each A/D at 1MHz, simultaneously, for an aggregate speed of 2MHz.

Also provided are four general purpose digital inputs and four high-current digital outputs. The inputs and outputs can be configured for 10k ohm pull-up or pull-down resistors (inputs and outputs are separately configurable).

The A/D conversion process is initialized by software control and can be started either by software command or digital input trigger via the right angle I/O header connector. Two status signals are provided at the I/O header; one indicates conversions are enabled; the other indicates the board's FIFO is almost full. Each sample acquired includes both of the analog input channels and the four digital inputs simultaneously. All data acquired by the board is time stamped with µsecond resolution.

The board is designed to be used in rugged industrial environments but is small enough to fit nicely onto any desk or testing station. The module is PC/104 sized (3.550 by 3.775) and ships standard inside a steel powder-coated enclosure with an anti-skid bottom.

OEM USB/104 FORM FACTOR

The OEM (board only) version is perfect for a variety of embedded applications. What makes the OEM option unique is that its PCB size and pre-drilled mounting holes match the PC/104 (3.550 by 3.775 inches) form factor (without the bus connections). This ensures easy installation using standard standoffs inside most enclosures or systems. For embedded OEM applications, a miniature USB input header is provided in parallel with the type B connector.

ACCESSORIES

We provide a variety of cables, terminal boards and mounting provisions such as the MP104-DIN for convenient DIN-Rail mounting.

SOFTWARE

The USB-AI16-2A utilizes a high-speed custom function driver optimized for maximum continuous data throughput of 4 MB/s that is hundreds to thousands of times faster than the USB human interface device (HID) driver used by some competing products. This approach maximizes the full functionality of the hardware along with capitalizing on the advantage of high-speed USB 2.0. The module is supported for use in most USB supported operating systems and includes a free Linux and Windows compatible software package. This package contains sample programs and source code in C#, Delphi and Visual C++ for 32-bit and 64-bit Windows. Also incorporated is a graphical setup program in Windows. Third party support includes a Windows standard DLL interface usable from the most popular application programs, and includes LabVIEW VIs. Embedded OS support includes the family of Windows Operating Systems including IoT.
