Extend the LM358 op-amp family’s output voltage range by cascading the op-amp with a few simple, inexpensive components.

One of the most common requests I get from engineers is for a comparison of voltage-feedback op amps and current-feedback op amps. It is impossible to determine which one better suits a given ...

The very basics of operational amplifiers. Learn comparator, inverting, and non-inverting op-amp configurations. An operational amplifier, or op amp, is a dc-coupled high-gain electronic voltage ...

Fig 1. This modified Wien-Bridge oscillator has three output states—high, low, and oscillation—that depend on the input voltage. It drives a bi-color LED to provide a visual indication of the input’s ...

You can take an op amp with rare input characteristics and elevate it to achieve higher voltage range, better gain accuracy, higher slew rate, and less distortion than the original op amp. I was ...

A dual precision op amp from STMicroelectronics is designed to have a low and temperature-stable input-offset voltage. The TSZ182 op amp has a chopper-stabilised design and a 3MHz gain-bandwidth. The ...

My hands-on introduction to operational amplifiers was in 1969 while in the army as a junior scientist in the Atmospheric Science Laboratory at the White Sands Proving Grounds. We had taken a ...

STMicroelectronics has introduced two new families of low power operational amplifiers which it claims provide enhanced accuracy and reduced package size. According to ST, its TSV85x and LMV82x ...

Power operational amplifiers (POPs) are becoming increasingly common in control circuitry. Their primary advantages over conventional amplifiers are reduced part counts, increased reliability, and ...

In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input ...
