• USB A/D measurement module incl. D/A converter
• 4 A/D channels (14 Bit resolution using differential-ended Modus) or
• 8 A/D channels (13 Bit resolution using singel-ended Modus)
• 2 D/A channels (10 Bit resolution)
• 24 TTL I/O
• 2 Counter

This professional USB AD/DA module provides up to 8 AD channels and 2 DA channels, which are capable to convert signals with up to 14 bit.
The USB-AD8DAC2/14 also has 24 TTL I/O channels, and two 32 bit counters onboard. The counter has a maximum frequency of 1MHz. Both, TTL I/O and counters are easily accessible through the 37 pole female D-SUB connector.

A/D Modes
Using the USB-AD8DAC2/14 two A/D modes are provided.

Differential ended mode with 4 A/D channels and a 12 Bit resolution
Single ended mode with 8 A/D channels an a 11 Bit resolution

The mode may be easily changed by supported driver functions.

Analog-To-Digital-Conversion
The USB-AD8DAC2/14 needs 20µs coversion time in differential ended mode by using one of the following measurement ranges: +/- 20V, +/- 10V,+/- 5V, +/- 4V, +/- 2,5V, +/- 2V, +/- 1,25V, +/- 1V.

Sindle ended mode uses a measurement range of +/-0..10V by using the same conversion time.

Digital-To-Analog-Conversion
The 2 D/A outputs provide a 10 Bit resolution with a voltage range of +0..5V and may be charged with up to 10mA.

Softwaresupport
Through implementation of this module into the QLIB (QUANCOM Driver Library) no knowledge in driver programming is needed and an easy to use programming API for Windows 95-Vista is provided. By using the QLIB it is easy and fast to develop applications using modern comilers like Delphi, Visual Basic, Visual Basic.NET, Visual-C, C#, C/C++ or graphical IDE i.e. Agilent VEE and LabView. Sample projects for the most languages are located on the driver CD and on this website.
