产品描述
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 to a 4Ω load with less than 10% distortion (THD) from a 5V battery voltage. It operates from 2.5V to 5.5V power supply.
The SGM 4871’ s micro-power shutdown mode (I SD = 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.
The SGM4871 is unity-gain stable and can be configured by external gain-setting resistors. Additionally, the SGM4871 features an internal thermal shutdown protection mechanism.
The SGM4871 is available in Green SOIC-8 and SOIC-8 (Exposed Pad) packages. It operates over an ambient temperature range of -40 °С to + 85 °С .
