... The classical single- ended amplifier configuration where one side of the load is connected to ground requires large, expensive output cou- pling capacitors. A configuration, such as the one used in the LM4912, has a major advantage over single supply, single-ended amplifiers. Since the outputs ...

... Application Information MUTE When in C-CUPL mode, the LM4912 also features a mute function that is independent of load impedance and enables extremely fast turn-on/turn-off with a minimum of output pop and click. The mute function leaves the outputs at their bias level, thus resulting in higher power consumption than shut- down mode, but also provides much faster turn on/off times ...
