ADVANTAGES OF VOLTAGE FOLLOWER
Voltage Follower: Buffering Powerhouse! High input impedance protects your source, while low output impedance drives loads effortlessly.
Voltage Follower
- A voltage follower is an op-amp circuit whose output voltage is equal to the input value (it "follows" the input voltage).
- As a result, a voltage-follower op-amp has a voltage gain of one and fails to improve the input signal.
- The voltage follower does not offer attenuation or amplification; it only serves as buffering.
- The input impedance of a voltage-follower circuit is quite high.
- Because of this property, it is a common option in a wide range of circuits that require isolation between the input and output signals.
- It is important to remember that Ohm's rule supports a voltage follower.
Advantages of Voltage Followers
- Offers power and current gain.
- Low output impedance for the circuit that employs the voltage follower output.
- The op-amp consumes no current from the input.
- Loading effects are avoidable.
Applications of Voltage Followers
- Buffers for logic circuits.
- Used in sample and hold circuits.
- In the active filters.
- Using a transducer in bridge circuits.
