An electronic circuit that amplifies the difference between two voltages. With one regular input and one inverting input (+ becomes -, - becomes +), it multiplies the difference by a constant factor.

Analog Devices, Inc. (ADI), introduced a dual-channel differential amplifier for driving high speed 12- to 18-bit A/D converters. Featuring a 3dB bandwidth of 4.5 GHz, the ADL5566 differential ...

A general method for measuring AC high voltages is to use a voltage divider, with two resistors in series. The resistors are selected so across one of the elements is some arbitrary fraction (like ...

Fully differential amplifiers have grown in popularity because of their low distortion, excellent noise rejection, and the simplicity of interfacing them with differential analog-to-digital converters ...

A research group succeeded in developing the world's thinnest and lightest differential amplifier for bioinstrumentation. Conventionally, bioinstrumentation circuits for health care and medical use ...

One of my first jobs as a freshly minted graduate engineer involved the maintenance of a set of analogue chart recorders. They were museum pieces by the early 1990s: a motorized roll of graph paper ...

The all-in-one Dynamics 4290 accelerometer/microphone and differential amplifier has both constant current operation and DC/AC amplification, automatic calibration ...

Accurately measuring current flow is a standard requirement in several applications (Fig. 1). Depending on the specific need, the options available to designers can include discrete designs assembled ...

If you’re the sort who finds beauty in symmetry – and I’m not talking about your latest PCB layout – then you’ll appreciate this clever take on the long-tailed pair. [Kevin]’s video on this topic ...
