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.
Range Frequency Current THD+N (2 years)
1.25 A 55 Hz 0.25 A < 0.25 %
0.5 A < 0.07 %
1.25 A < 0.07 %
12.5 A 55 Hz 1 A < 0.10 %
5 A < 0.05 %
12.5 A < 0.05 %
Note: These values are also guaranteed between 10 Hz and 100 Hz by design.
