Using a complementary silicon-germanium and CMOS technology, Texas Instruments has built a fully-differential op-amp that is optimised for driving high-speed analogue-to-digital converters at up to ...

The LMH6554 is a high performance fully differential amplifier designed to provide the exceptional signal fidelity and wide large-signal bandwidth necessary for driving 8 to 16 bit high speed data ...

Analog Devices has released a set of differential-in differential-out amplifiers win a minimum CMRR (common-mode rejection ratio) of 94dB. Based on the existing LTC6363 differential amplifier which ...

Texas Instruments has introduced a fully-differential op-amp for driving fast ADCs up to 100MHz, claiming it to be the lowest noise, lowest distortion amplifier of its type. Built on the firm’s ...

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 ordinary modern IC op amp is fully applicable to most standard amplifier configurations. Error sources are small and may be of no concern, or one can easily ...

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 ...

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 ...

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.
