By using op amps powered from a bipolar supply and ground-referencing the sensor signals, the op amp’s output will be at zero ...

The circuit is based upon a design from the 1990s which as far as we can see is a pretty conventional non-inverting amplifier. It has an on-board op-amp to create a virtual ground, and three ...

Analog Devices has created a fast power op-amp that can handle ±55V rails and ±1A outputs, with a digital control bus for ...

Figure 1 This is the generic op amp inverter circuit. Figure 2 Here is the classic operational amplifier differentiator circuit, with inverting output. The time domain operation of the differentiator ...

One of my previous columns explains a method for calculating decreasing open-loop-gain-induced errors (Reference 1). Several readers requested a simpler error-function explanation, so this one uses op ...

You think of op amps as amplifiers because, no kidding, it is right in the name. But just like some people say, “you could do that with a 555,” [Doctor Volt] might say, “you can do that with ...
