Notes
1. The circuit is DC adjusted at V_P = 6 to 18 V and AC operating at V_P = 8.5 to 18 V.
2. At 18 V < V_P < 30 V the DC output voltage ≤ V_P/2.
3. Output power is measured directly at the output pins of the IC.
4. Frequency response externally fixed.
5. Ripple rejection measured at the output with a source-impedance of 0 Ω, maximum ripple amplitude of 2 V (p-p) and
at a frequency of between 100 Hz and 10 kHz.
6. Noise measured in a bandwidth of 20 Hz to 20 kHz.
7. Noise output voltage independent of R_s (V_I = 0 V).
