1. What is Common Mode Rejection Ratio (CMRR) and why is it important for instrumentation amplifiers?
CMRR indicates an instrumentation amplifier's ability to suppress common mode signals, with higher values being better. A high CMRR is especially important in noisy environments to ensure that the amplifier primarily amplifies differential signals and is not affected by common mode interference.
-
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 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.
