Abstract :
An investigation is made into the possibility of fully integrating an instrumentation amplifier in monolithic form. Of many types of instrumentation amplifiers, the one with voltage-to-current conversion appears to be most suitable for monolithic integration. For a low price per unit the number of components external to the IC must be low. A circuit configuration which requires only two external resistors to fix the amplification factor accurately is the differential-difference amplifier (DDA). This configuration possesses some particularly useful applications.
