Input Offset Voltage

Input offset voltage is a measure of the voltage difference between the noninverting and inverting input sources in a closed loop circuit, with the operational amplifier operating in its linear region. The offset voltage will appear as a DC offset in the output equal to the input offset voltage, multiplied by the gain of the circuit. The input offset voltage is also affected by the Common-mode voltage. The OPA module is factory calibrated to minimize the input offset voltage.
