1. How do instrumentation amplifiers handle sensor signals?
Instrumentation amplifiers are used to extract low-level signals from sensors (e.g. thermocouples, pressure sensors) to provide high-precision amplification, and are particularly suited to applications that require accurate reading and amplification of weak signals, such as medical and industrial monitoring.
-
2. 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.
-
3. What is Slew Rate and how does it affect op amp performance?
Slew rate is the maximum rate of change of an operational amplifier's output voltage over time. Higher slew rates are good for fast-changing signals and can handle higher frequency inputs, while lower slew rates can cause signal distortion.
-
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.
