Notes
1. The internal circuit impedance at pin 11 is > 5 kif V11 > V10.
2. Closed loop voltage gain can be chosen between 32 and 56 dB (BTL), and is determined by external components.
For further gain reduction see Application Report.
3. Frequency response externally fixed.
4. The input impedance in the test circuit (Fig.3) is typ. 100 k.
5. Supply voltage ripple rejection measured with a source impedance of 0 (maximum ripple amplitude: 2 V).
6. Output power is measured directly at the output pins of the IC.
7. Closed loop voltage gain can be chosen between 26 and 50 dB (stereo), and is determined by external components.
8. A resistor of 56 kbetween pins 3 and 7 to reach symmetrical clipping.
9. Without bootstrap the 100 µF capacitor between pins 5 and 6 (8 and 9) can be omitted. Pins 6, 8 and 10 have to be
interconnected.
