Input bias current and input offset current also affect the net offset voltage seen for a given amplifier. Chopper amplifiers actively measure and compensate for the input offset voltage, and may be used when very low offset voltages are required. However, the input offset voltage value may drift with temperature or age. This can be reduced to several microvolts if nulled using the IC's offset null pins or using higher-quality or laser-trimmed devices. The input offset voltage ( V o s are around 1 to 10 mV for cheap commercial-grade op-amp integrated circuits (IC).
