The op amp-based current sensing circuit described here is not new, it has been around for some time, but with very little discussion of the circuit itself. Somewhere along the line it was informally ...

In previous articles—Common op-amp circuits, Op amps do integration, and The practical op-amp differentiator is quite versatile—we looked at some classic op amp circuits. These circuits used negative ...

Circuit simulations are great because you can experiment with circuits and make changes with almost no effort. In Circuit VR, we look at circuits using a simulator to do experiments without having to ...

Designed specifically for high-voltage sensing, a new generation of optically isolated amplifiers make monitoring and system protection circuits more accurate and easier to design. These iso-amps can ...

Maybe you are familiar with the op-amp as an extremely versatile component, and you know how to quickly construct a huge variety of circuits with one. Maybe you even have a favorite op-amp or two for ...

This file type includes high resolution graphics and schematics when applicable. A piezoelectric motor is a linear motor with bidirectional motion. It uses friction to grip the armature while a ...

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 ...

b. The gain is set by VCC as the higher the supply voltage, the higher the gain. c. By the value of R3 as this resistor to ground sets the offset bias seen by the op-amp hence the gain. d. By the ...

With its 1.2 x 1.3mm outline and typical current of 900nA, the TSU111 nano-power op amp from STMicroelectronics is said to help cut the size and energy needs of analogue circuits in a range of ...

Rohm is aiming at high-accuracy sensing with a low-noise CMOS op-amp. Accelerometers used in sonar systems and optical sensors are potential applications. LMR1802G-LB achieves input equivalent noise ...
