(Editor's note: the op amp is a basic building block of the analog world and analog circuitry. Despite its extremely simple functional block diagram, it has many operating parameters from critical to ...

Building on last month’s discussion of resistor noise, let’s check out some basics of amplifier noise. The non-inverting op amp configuration is most common for low noise applications so we’ll make ...

Switching regulators have delivered such convenience and efficiency compared to their linear siblings, that it’s now becoming rare to see an old-style three-terminal regulator. Modern designs have ...

A simple linear voltage-controlled amplifier can be constructed with one op amp and two JFETs (see the figure). The amplifier can achieve an 80-dB dynamic control ...

How do you get the input of an op-amp to work below the negative-most supply rail?, I asked. Now I know – thanks to the patience of ADI field application engineer Andreas Koch. It was not just any ...

The ADHV4710 op amp operates on dual supplies from ±12 to ±55 V, delivering output current of ±100 mA at the higher voltages. A ±1,300-V/μs output slew rate into capacitive loads up to 1 nF (1000 pF).
