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 ...

Tucson, Ariz. – Apex Microtechnology touts its PA38 and PA39 high-voltage MOSFET power op-amp boards- built with SMT components on a thermally conductive but electrically isolated substrate-as a ...

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 ...

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

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 ...

Are your jellybeans getting stale? [lcamtuf] thinks so, and his guide to choosing op-amps makes a good case for rethinking what parts you should keep in stock. For readers of a certain vintage, the ...

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 ...
