GENERAL DEscriptION
The SGM4895 is a fully differential audio power amplifier which operates from 2.5V to 5.5V power supply. It can deliver 1.3W into a 8Ω load from 5V supply at THD+N = 1%. It is designed for portable applications.
The SGM4895 has pop/click suppression circuitry, low power consumption shutdown mode and thermal shutdown protection.
Bootstrap capacitors or output coupling capacitors are not needed.
The SGM4895 is available in Green TDFN-3×3-8L and MSOP-8 (Exposed Pad) packages. It operates over an ambient temperature range of -40℃ to +85℃.
