NOTE 3: Clamp transistors are included that prevent the input voltages from swinging below ground more than approximately – 0.3 V. The
negative input currents that may result from large signal overdrive with capacitive input coupling must be limited externally to values
of approximately – 1 mA. Negative input currents in excess of – 4 mA causes the output voltage to drop to a low voltage. These
values apply for any one of the input terminals. If more than one of the input terminals are simultaneously driven negative, maximum
currents are reduced. Common-mode current biasing can be used to prevent negative input voltages.
