Waltham, Mass. — Instrumentation amplifiers (in-amps) are specialized, precise-gain op amps with a challenging task: They take a low-level input signal, such as an EEG or strain gage, which is ...

The THS4531 is a low-power, fully-differential op amp with input common-mode range below the negative rail and rail-to-rail output. The device is designed for low-power data acquisition systems and ...

The AD628 common-mode differential amplifier is said to be the first such device to provide programmable gain. Using an external resistor, the amplifier can be set for a gain range from 0.1 to 1,000.

Differential amplifier circuits, such as the one illustrated in Figure 1, are required in analogue technology for a wide variety of applications. One example is measurement technology in which, ...

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 ...

Design analysis of the K2-W Vacuum Tube Op Amp’s design and operation reveals the mad science that created a commercial revolution in 1950s and 1960s analog computing. Op amps played a critical role ...

This article started because a good friend of mine dropped a Panasonic SA-XR50 switch-mode amplifier to me for some basic bench test. This article will NOT be a review of that unit, but an ...
