What is Instrumentation amplifier?


Answer: An instrumentation amplifier is basically a difference amplifier which must satisfy the following requirements-

DRex Electronics
  • 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.
