LMH6703 SNOSAF2D – FEBRUARY 2005 – REVISED MARCH 2013 www.ti.com Disabled, the LMH6703 inputs and output become high impedances. While disabled the LMH6703 quiescent current is approximately 200 µA. Because of the pull up resistor on the shutdown circuit, the ICC and IEE currents (positive and negative supply currents respectively) are not balanced in the disabled state. The positive supply current (ICC) is approximately 300 µA while the negative supply current (IEE) is only 200 µA.
