The input offset current (IOS) is equal to the difference between the input bias current at the non-inverting terminal (IB+) minus the input bias current at the inverting (IB- ) terminal of the amplifier. Offset current is typically an order of magnitude less than bias current.
What is the formula for input offset current?
The input offset current, IOS, is the difference between IB– and IB+, or IOS = IB+ - IB–.
Why input offset current is important?
Input bias current is a usually overlooked amplifier parameter that can have a significant effect on an amplifier circuit's output accuracy. Sometimes the effect is small enough to be ignored, but sometimes it can cause a circuit to fail entirely.
