unless otherwise speci?ed 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. 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 ? (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 to

20 Hz to

20 kHz. 9. Noise output voltage independent of RS (VI =

0 V). PARAMETER CONDITIONS SYMBOL MIN. TYP. MAX. UNIT BTL application Output power note
