What is Instrumentation amplifier?
Answer: An instrumentation amplifier is basically a difference amplifier which must satisfy the following requirements-
- Precise low level signal amplification.
- Low noise. Low thermal drift.
- High input resistance.
- Low power dissipation.
- High CMRR.
- High slew rate.
This amplifier amplifies the low level output signal of the transducer to such a level that it can drive the indicator or display.
