A voltage clamping system includes: (a) a first electronic device connected to a first power source and having a signal output node, a voltage clamp high node, and a voltage clamp low node, wherein the voltage clamp high node and the voltage clamp low node are coupled to a second power source different than the first power source; and (b) a second electronic device powered by the second power source and having a signal input node coupled to the signal output node of the first electronic device. The signal output node of the first electronic device is passively clamped, with low distortion, approximately rail-to-rail with respect to the second power source such that the second electronic device is protected from damage due to excessive voltage levels.
