The quiescent output voltage typically equals 1/2 the normal VCC voltage = 1 Volt. When driving a 16 load, the nominal VCC is 24V. When driving a 16 load, the maximum low level distortion is reduced to 0.50%. Tested at VCC equals nominal and measured in watts (rms). 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.
