Differential Amplifier
overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
A differential amplifier is a type of electronic amplifier that amplifies the difference between two input voltages while rejecting any signals that are common to both inputs.
Key Features
- High input impedance
- Low output impedance
- High common-mode rejection ratio
- Gain control ability
Pros
- High precision amplification of small signal differences
- Effective in rejecting noise and interference from common-mode signals
- Useful in instrumentation and measurement applications
Cons
- Requires careful design and matching of components for optimal performance
- Can be sensitive to temperature variations and drift
