Op amps, those versatile building blocks of the analogworld, come in thousands of varieties. Yet there’sstill a need for more and better, in which “better”means units with more desired attributes but ...

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 ...

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 ...

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 ...

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...

Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with our op amp quiz; answer explanations are included. By 1969, a fledgling ...

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.
