8.3.3 Overload Power Limiter

In many bipolar-based amplifiers, the output stage of the amplifier can draw significant (several milliamperes) of quiescent current if the output voltage becomes clipped (that is, the output voltage becomes limited by the negative or positive supply voltage). This condition can cause the system to enter a high-power consumption state, and potentially cause oscillations between the power supply and signal chain. The OPAx205 have an advanced output stage design that eliminates this problem. When the output voltage reaches either supply (V+ or V–), there is virtually no additional current consumption from the nominal quiescent current. This feature helps eliminate any potential system problems when the signal chain is disrupted by large external transient voltage.
