Does op-amps use internal capacitive coupling between stages?
No. An op-amp is a DC coupled device.
Real world op amps have infinite gain?
Real world op amps have very high gain, but they do not have infinite gain.
What does the OP stand for in OP amps?
Op amps stands for operational amplifier. An operational amplifiers is a high gain voltage amplifier that requires a differential input and produces single outputs.
What is the error voltage in op amps?
The amount by which it deviates from ideal.
What is drift in op amps?
Drift in op amps refers to changes in the output voltage or other characteristics over time or due to environmental factors like temperature. It can affect the precision and stability of the op amp's operation, making it important to consider when designing circuits for high accuracy applications. Techniques such as using precision op amps or implementing compensation measures can help minimize drift effects.
Can an op amp be powered with 6 volts?
Yes. The first generation of op amps worked from +15 and -15 volt supplies. You can now get low-voltage and micropower op amps that work on single supplies, and on low-voltage supplies. Look for: low power op amp on the web, or check out your local electronics store - one that actually sells parts, not just equipment.
A differential amplifier is used In input stage of op-amps to achieve very high?
CMRR
Circuits with op-amps?
What about 'em? There's more circuits than I could even begin to describe from DC to RF. Depends on what you want to do as to what type to use and what design is needed.
What are the inputs to an op amp?
Power Supply Pins: Op-amps require power to operate. They have positive and negative power supply pins (+V and -V) that provide the necessary power levels for the op-amp to function. Output Pin: The output pin provides the amplified or manipulated signal based on the inputs. It's where the result of the op-amp's operation is obtained. Offset Null or Offset Adjustment Pins: Some op-amps have offset null pins that can be used to adjust the output offset voltage. This is useful for minimizing any unwanted voltage offset in the output. Frequency Compensation Pins: In some op-amps, additional pins are used for frequency compensation to ensure stable operation in high-frequency applications. Balance or Trim Pins: These pins are used in op-amps that are intended to be used in bridge or differential amplifier configurations, where precise balance between inputs is necessary.

What is lm324 IC?
LM324 is a 14pin IC consisting of four independent operational amplifiers (op-amps) compensated in a single package. Op-amps are high gain electronic voltage amplifier with differential input and, usually, a single-ended output. The output voltage is many times higher than the voltage difference between input terminals of an op-amp.These op-amps are operated by a single power supply LM324and need for a dual supply is eliminated. They can be used as amplifiers, comparators, oscillators, rectifiers etc. The conventional op-amp applications can be more easily implemented with LM324.
How does one know the range of frequencies where one can apply an operational amplifier in a measurement circuit?
Sir: You can't know. The technical specification for OP Amps is not marked on the OP Amp chip. You need to consult an IC Master book or search the internet for "Op amps" and find one that will cover the frequencies you need covered. Then you have to find a supplier. Some libraries have an IC master. Luck
