Single Ended vs Differential Inputs

One of the most common questions asked is the difference between single-ended and differential signals inputs, and what applications they should be considered in. It is important to know the difference between single-ended and differential inputs as it can greatly affect the quality of your data Differential signaling is a method for electrically transmitting information using two complementary signals . The technique sends the same electrical signal as a differential pair of signals, each in its own conductor. The pair of conductors can be wires (typically twisted together) or traces on a circuit board. The receiving circuit responds to the electrical difference between the two signals, rather than the difference between a single wire and ground . The opposite technique is called single-ended signaling. A single-ended input measures the voltage difference between a wire and the ground. This difference is then amplified to provide the output.
