The SGM4865 is a stereo audio power amplifier which operates from 2.6V to 5.5V supply voltage. It can deliver 2.6W into a 4Ω load from 5V supply at THD+N = 1%. It is designed for portable applications. The external gain-setting resistors can configure the unity-gain stable of the device.
The SGM4865 has pop/click suppression circuitry, low power consumption shutdown mode and thermal shutdown protection.
The SGM4865 is available in a Green TQFN-4×4-16L package. It operates over an ambient temperature range of -40℃ to +85℃.
