SGM4871

SGM4871 2.4W Audio Power Amplifier with Shutdown Mode GENERAL DESCRIPTION The SGM4871 is a mono bridged audio power amplifier that is designed for portable communication device applications and demanding applications in mobile phones. SGM4871YPS8 is capable of delivering 2.4W of continuous average power into a 4Ω load with typically 10% distortion (THD+N) from a 5V battery voltage. It operates from 2.5V to 5.5V power supply. The SGM4871’s micro-power shutdown mode (ISD = 0.07µA TYP) is activated when V+ is applied to the SHDN pin. Since the SGM4871 does not require output coupling capacitors, bootstrap capacitors, or snubber networks, it is ideally suited for low power portable systems that require minimum volume and weight.
