Instrumentation Amplifier

- Amplifier used in the field of Instrumentation (acquiring physical signals, convert it to electrical signals by Transducer and this electrical signal is too weak; so need amplification).

Features:
1. Very high Gain
2. Very high CMRR
3. Very high Input Impedance
4. Very low Output Impedance
5. Very low dc offset

- Initially, a Differential Amplifier is taken.. 

- To attain all these features, a buffer is added to each input side of OpAmp 741.


Application:
