1. 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.
-
2. 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.
-
3. What are the main application scenarios of Op Amps?
Operational amplifiers are widely used in signal conditioning, voltage follower, filter, comparator, integrator, differentiator, precision level shifter and other circuits, which are widely used in consumer electronics, industrial automation, and instrumentation.
-
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.
