1. What is an operational amplifier and how does it work?
An operational amplifier (Op Amp) is a high-gain voltage amplifier with differential input and single-ended output, which is commonly used for analog signal processing functions such as amplification, filtering, integration, and differentiation.
-
2. How to choose the right operational amplifier?
Parameters such as input offset voltage, input bias current, gain bandwidth product, slew rate, noise characteristics, supply voltage, and power consumption should be considered when selecting an operational amplifier to meet the needs of a particular application.
-
3. What is the effect of the op amp's out-of-range voltage on accuracy?
An out-of-phase voltage is the difference in voltage at which the output is not zero when the signal at the input is zero. A large out-of-phase voltage reduces the accuracy of a system, especially in high-gain applications, and selecting an op amp with a low out-of-phase voltage can improve accuracy.
-
4. What are the application scenarios of buffer amplifiers?
Buffer amplifiers are commonly used in signal isolation, impedance matching, voltage follower and power amplification scenarios, and are suitable for protecting weak signal sources from load effects in signal processing chains.
