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.
