Differential Line Drivers

Differential line drivers are electrical devices that convey analogue signals, audio or otherwise, across distances with minimal noise pick up.

How do differential line drivers work?

Information in differential line drivers is transmitted using two complementary signals. They send the same electrical signal as two different signals, each on a conductor of its own.The conductors can either be traces on a circuit board or wires that are twisted together.

The voltage between the two signals and not the difference between a single wire and earth (a common return path for electric current), prompts a response by the receiving circuit. Differential line drivers resist electromagnetic noise once the difference between wires has been detected by the receiving circuit.

What are differential line drivers used for?

Differential line drivers are utilised in balanced audio circuitry and digital signalling. They are used to reduce electromagnetic noise in applications such as portable and mobile devices where reducing the supply voltage results in reduced noise immunity, and in computers to reduce electromagnetic interference.

They can be built preferably around differential amplifiers fitted with high-speed, high-output current buffers inside the feedback loop.
