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 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 is a rail-to-rail operational amplifier and what are its advantages?
Rail-to-rail op amps are capable of extending the output voltage range to the limit of the supply voltage (i.e., the “rail”), allowing them to handle large dynamic range signals even at low supply voltages, making them particularly suitable for low-voltage power supply systems and portable devices.
-
4. Why do buffer amplifiers have high input impedance and low output impedance?
A high input impedance ensures that no load is applied to the preamplifier circuitry, preventing signal degradation, while a low output impedance provides a large driving capacity, ensuring that the signal can be passed on to subsequent circuits without loss.
