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. 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.

3. How are operational amplifiers used in filter circuits?
Operational amplifiers can be used to build a variety of active filter circuits, including low-pass, high-pass, band-pass, and band-reject filters, which are commonly used for noise removal and signal conditioning in signal processing.
-
4. 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.
