A typical circuit for the LM4916 two-channel amplifier

As shown in the figure shown for a typical circuit LM4916 two-channel amplifier.

Left and right channel audio signals are input LM4916 1,5 feet, after an internal amplifier output by a 9,7 feet, after coupling capacitor Co are added to the respective speakers. LM4916 2 pin external shutdown control, when 2 feet to VDD allowed to work; prohibit work then low, reduce chip power consumption. LM4916 3 feet squelch control, the mute mode, when the 3-pin low-level ban chip works to eliminate switching caused by "click - flapping" sound; allowed to work then high.
