For battery based applications, power consumption is a key issue, therefore the amplifier should be turned off when in the standby state. In order to eliminate any speaker sound bursts while turning the amplifier on, the application circuit, which will incorporate a capacitance value of C1, should be adjusted in accordance with the speaker s audio frequency response. A greater value of C1 will improve the noise burst while turning on the amplifier. The recommended operation sequence is:
