Abstract

An instrumentation amplifier with an electronically adjustable gain is disclosed. The gain is adjusted by electronically controlling a resistance coupled to a feedback portion of the instrumentation amplifier. The resistance is adjusted by switches controlled by resistor-control signals references to a common mode voltage appearing at the input of the instrumentation amplifier. Accordingly, the instrumentation amplifier is capable of accommodating a high voltage range of common mode voltages while still providing controllable gain.
