Note 4. It is defined by "offset voltage (Voff)" of transformer impedance amplifier. When beedback
resister is Rf. Input bias current is expressed by a following formula. Is= Voff/Rf
When using it as transformer impedance amplifier, "VCOM=VDD/2" are recommended.
Note 5. It does not contain output drive current.
