1. 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.
-
2. What is the effect of the op amp's out-of-range voltage on accuracy?
An out-of-phase voltage is the difference in voltage at which the output is not zero when the signal at the input is zero. A large out-of-phase voltage reduces the accuracy of a system, especially in high-gain applications, and selecting an op amp with a low out-of-phase voltage can improve accuracy.
-
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. 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.
