Operational amplifiers (op amps) are almost the perfect amplifier. As long as you keep a few important details in mind, their imperfections will seem invisible.

Understand the basics of op amps and their applications in circuit design. Learn how these devices function.

Most operational amplifiers (op amps) have input and output electrostatic discharge (ESD) protection diodes, as shown in Figure 1. These diodes are designed for protection from ESD damage during ...

The authors proposed and described the gallium arsenide (GaAs) operational amplifier (Op Amp) circuit engineering solution. This architecture is implemented on the basis of combined tech processes, ...

Accomplishing a true zero output of an op-amp with a symmetrical multivibrator for better efficiency than the previous photocell design idea.

An Arduino Shield to measure an FSR using either a buffered voltage divider or current to voltage op-amp solution. We needed is an instrument that can plot the voltage/thrust curve for any motor and ...

This circuit is an especially simple op-amp application, and is a typical one for a sensor interface where a DC voltage needs to be brought into range of a microcontroller.

This paper presents logarithmic amplifier based on operational floating current conveyor (OFCC) with both voltage and current modes of input. Logarithmic amplifiers are nonlinear circuits in which the ...

TSV782 is a new member of STMicro’s 5V op-amp family that enables designers to create circuits without trimming and calibration during production, which saves external components like precision ...

An app for desigining resistor network impedance in op-amp circuits based on desired noise floor Please note that the application is currently under heavy development.
