Which of the following is the property of instrumentational amplifier?

1.	Which of the following is the property of instrumentational amplifier?(a) Extremely low input impedance(b) High bias and offset currents(c) Low slew rate(d) Very high CMRRI had been asked this question during a job interview.Question is from Measurement of Hearing in division Audiometry of Biomedical Instrumentation
Answer» The CORRECT option is (d) Very high CMRR The best explanation: Instrumentational amplifiers have very high CMRR. Instrumentational amplifiers have EXTREMELY high input impedance. Instrumentational amplifiers have low bias and offset CURRENTS. Instrumentational amplifiers have high slew rate.
