1. 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.
-
2. What is a gain adjustable instrumentation amplifier?
Gain-adjustable instrumentation amplifiers allow the gain to be adjusted by external resistors or digital controls to accommodate the dynamic range of different signal sources. These amplifiers are commonly used in a variety of sensor systems.
-
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.
