* The internal base load is required to obtain a stable amplifier output voltage when no
external piezo load is connected. The total load is the sum of internal base load and external
piezo load. Note that the amplifier output power is allocated to the internal and external loads
according to their capacitance values. This is of particular importance under large-signal
conditions.
Examples: The small-signal capacitance of the connected piezo actuator is 550 nF, hence its
large-signal capacitance is approx. 1.1 μF (2 * 550 nF). Under large-signal conditions,
