Notes to the characteristics
1. The circuit is DC adjusted at VP = 6 V to 18 V and AC operating at VP = 8.5 V to 18 V.
2. At 18 V < VP < 30 V the DC output voltage ≤ VP/2.
3. Conditions:
a) V11 = 0 V
b) short-circuit to GND
c) switch V11 to MUTE or ON condition (rise time ≥ 10 µs).
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).
6. Frequency f = 100 Hz.
7. Frequency between 1 kHz and 10 kHz.
8. Noise voltage measured in a bandwidth of 20 Hz to 20 kHz.
9. Noise output voltage independent of RS (VI = 0 V).
