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 is the noise performance of instrumentation amplifiers optimized?
Select low-noise amplifiers in your design and use shielding, filters, and precise power management to minimize external noise. High-quality resistors should be used wherever possible and PCB layout should be optimized to reduce noise coupling.
-
3. What is an operational amplifier and how does it work?
An operational amplifier (Op Amp) is a high-gain voltage amplifier with differential input and single-ended output, which is commonly used for analog signal processing functions such as amplification, filtering, integration, and differentiation.
-
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.
