Description
The ADU73 Voltage Input to USB Interface features two, 0-5VDC inputs that can be used for ratiometric or absolute measurements. Ideal for use with resistive sensing devices including linear potentiometers, string pots, thermistors etc.
Features a 5.000V reference output (20mA) for biasing of external sensors to facilitate ratiometric measurements. Exceptional resolution, and low noise 24-Bit sigma-delta A/D with sample rates up to 1000s/s for a single channel or 500s/s for two channels.
This low-cost Voltage Input to USB Interface is easy to use with VB, VB.NET, Visual C++, C , MATLAB, LABView etc. via standard HID drivers included with Windows.
A mini-driver (DLL)* is also provided, allowing control using standard ASCII commands using familiar readfile and writefile commands.
The ADU73 includes a 10' USB cable and is available in a flange mount enclosure or a DIN rail mount option.
