Description
The ADR7700 is an high resolution/accuracy, build-to-order data acquisition interface designed primarily for OEMs.
Each unit is scaled and calibrated to customer specified input ranges.
This low-cost build-to-order serial data acquisition interface is easy to use with Visual Basic, Basic, C, Visual C++, Labview, Testpoint, or other high level languages that allow access to a serial port.
