2.6W Stereo Audio Power Amplifier
The SGM4888 is a dual bridge-connected audio power amplifier which operates from 2.8V to 5.5V supply voltage. It can deliver 2.5W into a 3Ω load or 2.1W into a 4Ω load from 5V supply at THD+N = 1%.
The SGM4888 integrates dual bridge speaker amplifier and stereo headphone amplifier on one chip to simplify design.
The SGM4888 has pop/click suppression circuitry, low power consumption shutdown mode and thermal shutdown protection.
The SGM4888 is available in a Green TQFN-4×4-24L package. It operates over an ambient temperature range of -40℃ to +85℃.
Supply Voltage Range: 2.8V to 5.5V
