8.3.2 Output Stage

The OPAx863 feature a rail-to-rail output stage with possible signal swing from VS– + 0.2 V to VS+ – 0.2 V. Violating the output headroom of either supply causes output signal clipping and introduces distortion.

The OPAx863 integrate an output short-circuit protection circuit that makes the device rugged for use in real-world applications.
