1. 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.
-
2. How can I reduce noise in operational amplifier circuits?
Noise can be reduced by selecting low-noise operational amplifiers, optimizing circuit layout, reducing power supply ripple, using appropriate decoupling capacitors, and adding filters where necessary.

3. What is a Buffer Amp and what is its function?
A Buffer Amp is an amplifier with a unit gain that is mainly used in voltage follower circuits to provide a high input impedance and a low output impedance to isolate the signal source from the load and prevent signal distortion or attenuation.
-
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.
