The typical circuit diagram of LM4916 for binaural amplifier

Published:2011/8/22 22:18:00 Author:Rebekka | Keyword: Two-channel amplifier | From:SeekIC

Pin 1 and 5 of LM4916 are inputed seperately by left and right channel audio signals and outputed respectively by pin 9, 7 after being amplified by the internal amplifier. Through Coupling capacitor Co adding to since channel speaker. The pin 2 of LM4916 connects shutdown control. It is allowed to work when pin 2 connects with VDD; It is not allowed to when it connetcs to a low level or it will decrease chip power consumption. The pin3 of LM4916 is squelch control. It is squelch mode when pin 3 connects to a low level. In order to eliminate the Cameroon - flapping sound that caused by switching transitions. It is allowed to work when it connects to a high level.
