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