INA102 interior contains three integrated op-amp and resistance components. It has the ability of differential signal amplifier faint. It is often used as the data detection system preamplifier. When the voltage smaller (such as Av amplification times more than 10), the voltage and drift of disorders such as INA102 index can meet the requirements. When the voltage magnification is large (such as Av > 100 large). The bias current imbalance causing disorder voltage error will be bigger. It often uses graph (c) shows circuit to adjust the imbalance INA102 voltage.
