1. What is the difference between an instrumentation amplifier and an operational amplifier?
Instrumentation amplifiers integrate multi-stage operational amplifiers for precise amplification of differential signals, while operational amplifiers are more versatile and can perform a wide range of analog signal processing tasks. Instrumentation amplifiers have higher input impedance and better common mode rejection.
-
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.
