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 differential probe, a device for measuring the voltage between two points in a circuit rather than the voltage between a point and ground, it an extremely useful addition to any electronics bench.

Debuting as a unique level-shifting difference amplifier, the INA159 delivers a gain of 0.2 and interfaces ±10V signals to single-supply a/d converters, particularly those with 4.096V or 5V references ...

Evaluating the error frequency responses of a fully differential amplifier can be difficult and time consuming if standard measurement techniques are used. This is ...

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 ...

ADL5580 is a SiGe dc to 10.0GHz differential-in differential-out gain block from Analog Devices, which has a digital bus for signal path tweaking. “The amplifier offers a referred-to-input noise ...

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 ...

If you’ve ever wondered why an op amp has the little plus and minus symbols on it, its because at the heart of it, the device is a differential amplifier. The problem is that — ideally, at least — it ...
