SGM4865 Overview

2.6W Stereo Audio Power Amplifier 2.6W audio amplifier

Features

Product Name: 2.6W Stereo Audio Power Amplifier

Product model: SGM4865

Product Description:

The SGM4865 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 2.6W of continuous average power per channel into a 4Ω Load with 10% distortion (THD+N) from a 5V power supply.

The SGM4865 features an externally controlled, low-power consumption shutdown mode and thermal shutdown protection. It also utilizes circuitry to reduce "clicks and pops" during device turn-on.

The SGM4865 is unity-gain stable and can be configured by external gain-setting resistors.

The SGM4865 is available in Green TQFN-4×4-16L package. It operates over an ambient temperature range of -40°C to +85°C
