are valid with no load on the voltage amplifier.
3.4.3 Total harmonic distortion and noise (THD+N)
The output signal quality depends on the design of the amplifier and its power supplies. The THD+N
values are not subjected by a long-term drift. The following guaranteed THD+N points are verified
during production using a measurement bandwidth of 20 kHz.
