Figure 2. Block Diagram
This device contains circuitry to protect the inputs against damage due to high static voltages or electric fields; however, it is advised that
normal precautions be taken to avoid application of any voltage higher than maximum rated voltages to this high impedance circuit. For
proper operation it is recommended that V
IN
and V
OUT
be constrained to the range V
SS
≤
(V

or V

)
≤
