功能特点

产品名称：1.1W Stereo Audio Power Amplifier 1.1W音频放大器

产品型号：SGM4992

产品描述：

The SGM4992 is a stereo audio power amplifier that is designed for demanding applications in mobile phones and other portable communication device applications. It is capable of delivering 1.1W of continuous average power per channel into an 8Ω Bridge Tied Load (BTL) with less than 1% distortion (THD+N) from a 5V power supply.

The SGM4992 features independent shutdown control for each channel and a low-power consumption shutdown mode, which is achieved by driving both shutdown pins with logic low. Additionally, it features an internal thermal shutdown protection mechanism.

The SGM4992 does not require output coupling capacitors or bootstrap capacitors, and therefore is ideally suited for mobile phone and other low voltage applications where minimal power consumption is a primary requirement.

The SGM4992 contains advanced pop & click circuitry which eliminates noise which would otherwise occur during turn-on and turn-off transitions.

The SGM4992 is unity-gain stable and can be configured by external gain-setting resistors.

The SGM4992 is available in Green TDFN-4×3-14L package. It operates over an ambient temperature range of -40°C to +85°C
