It supports an operating voltage of +3 to +32 volts (single power supply) or ±1.5 to ±16 volts (dual power supplies).
Input voltage can range from −0.3 to +32 volts with single power supply. Small negative input voltages below ground are acceptable because the bipolar junction transistors at the input stage are configured such that their base-emitter junction voltage provides just enough voltage differential between the collector and base for the transistors to function.[2]
