1. How to choose the right instrumentation amplifier?
The input common-mode voltage range, gain-bandwidth product, noise performance, power consumption, temperature drift, and common-mode rejection ratio (CMRR) should be considered when selecting an instrumentation amplifier to ensure that it meets the accuracy requirements of a particular application.
-
2. How do instrumentation amplifiers handle sensor signals?
Instrumentation amplifiers are used to extract low-level signals from sensors (e.g. thermocouples, pressure sensors) to provide high-precision amplification, and are particularly suited to applications that require accurate reading and amplification of weak signals, such as medical and industrial monitoring.

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.
