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 achieve high accuracy and low drift in instrumentation amplifiers?
Select an amplifier with low bias current, low offset voltage, and low noise, and reduce the effect of temperature drift on accuracy through a stable power supply and proper temperature compensation circuit design.
-
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. How to choose the right operational amplifier?
Parameters such as input offset voltage, input bias current, gain bandwidth product, slew rate, noise characteristics, supply voltage, and power consumption should be considered when selecting an operational amplifier to meet the needs of a particular application.
