A balun may also be used instead of an active differential amplifier device.

The output of an ideal differential amplifier is given by:

A more realistic expression for the output of a differential amplifier thus includes a second term.

The top differential amplifier, whose output is referred to ground potential, has unitary gain.

Revision G replaced the input transformer with a differential amplifier.

The op-amp is one type of differential amplifier.

The name "differential amplifier" should not be confused with the "differentiator," which is also shown on this page.

Electronic balance, or active balance, is achieved using differential amplifiers at each end of the line.

Thus, when a differential amplifier is used to extract this difference, its output constitutes the low pass filter section.

Pairs of sensor elements may be wired as opposite inputs to a differential amplifier.

Such a situation does not usually define the need for an isolation amplifier, but rather a differential amplifier.

A non-isolated differential amplifier does not provide isolation between input and output circuits.

The input stage of modern amplifiers is usually a differential amplifier with a transconductance characteristic.

It also forms a building block for differential amplifiers and operational amplifiers.

This differential signal recombination can be implemented with a differential amplifier.

The input stage is a composed differential amplifier with a complex biasing circuit and a current mirror active load.

Many electronic devices use differential amplifiers internally.

With two inputs and two outputs, this forms a differential amplifier stage (Fig. 2).

The circuit includes two differential amplifiers.

The series included differential amplifiers.

High-gain differential amplifier with positive feedback.

By applying negative feedback, an op-amp differential amplifier (Fig. 4) with predictable and stable gain can be built.

Some kinds of differential amplifier usually include several simpler differential amplifiers.

A differential amplifier is used as the input stage emitter coupled logic gates and as switch.

Harkness uses the example of the differential amplifier, which is a basic component in instrumentation used to record and measure biological potentials.
