1. What is an instrumentation amplifier and what is it mainly used for?
An instrumentation amplifier is a high-precision amplifier designed to amplify low-level differential signals with high input impedance and high common mode rejection ratio (CMRR), and is commonly used in scenarios such as medical equipment, sensor signal processing, and industrial measurements.
-
2. 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.
-
3. 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.
-
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.
