Operational amplifiers
(63)Operational amplifiers are electronic circuits characterized by high voltage amplification and high input impedance. Currently, they are created as integrated circuits. A typical operating amplifier has two inputs (inverting and non-inverting) and one output. It’s designed to work with an external feedback system, on which its application depends as e.g., an inverting amplifier, non-inverting amplifier, or voltage follower. When selecting the amplifier, it’s worth analysing the most important parameters – input offset voltage, differential resistance, amplification bandwidth, voltage rise rate and cut-off frequency. The first parameter describes the voltage between inputs of the amplifier at the moment when there is zero voltage at the output. The elements available on the market differ in operating speed, frequency, mounting method and resistance to high temperature. The offer also includes analogue comparators, i.e. amplifiers that extremely quickly compare voltages or currents at the input and give a relevant signal at the output.
Operational amplifiers available at TME
TME distributes analogue and mixed circuits with various parameters. The catalogue includes over 1300 operating amplifiers, adapted for surface mount (SMD) and through-hole technology (THT). Search filters allow you to find components with specific gain, input offset voltage, bandwidth and operating voltage values. The components also feature different housing designations and operating temperatures. The offer also includes integrated circuits with specially improved parameters, such as low noise, high accuracy, and galvanic separation.
Transfer Multisort Elektronik offers amplifiers from manufacturers such as Analog Devices or Microchip Technology.
