These parameters are guaranteed by design and are tested only by sampling while mass production.

While a voltage source with large output impedance is measured by an instrumentation amplifier having input

bias current, an additional input offset voltage will be introduced. However, this offset voltage could be

cancelled by mirrored offset cancellation technique.
