The circuit is DC adjusted at V
Output power is measured directly at the output pins of the IC.
Frequency response externally fixed.
Ripple rejection measured at the output with a source impedance of 0 , maximum ripple amplitude of
2 V (p-p) and a frequency between 100 Hz and 10 kHz.
Noise voltage measured in a bandwidth of 20 Hz to 20 kHz.
Noise output voltage independent of R
