Note 1. The quiescent output voltage typically equals 1/2 the normal VCC voltage = 1 Volt.
Note 2. When driving a 16Ω load, the nominal VCC is 24V.
Note 3. When driving a 16Ω load, the maximum low level distortion is reduced to 0.50%.
Note 4. Tested at VCC equals nominal and measured in watts (rms).
Note 5. Measurement made with a 5µF capacitor from Pin1 to GND. Voltage at Pin14 is at a ripple
frequency of 60Hz.
Note 6. Unity gain occurs between 10 and 100MHz.
