Dual 2.1W Audio Power Amplifier Plus Stereo Headphone Function
GENERAL DESCRIPTION

The SGM4863 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%. It is designed for portable applications. When driving stereo headphones, the amplifiers can operate in single-ended mode at the headphone input pin.

The SGM4863 integrates dual bridge speaker amplifier and stereo headphone amplifier on one chip to simplify design.

The SGM4863 has pop/click suppression circuitry, low power consumption shutdown mode and thermal shutdown protection.

The SGM4863 is available in Green TSSOP-20 (Exposed Pad), TQFN-3×3-20L, TSSOP-16 (Exposed Pad), SOIC-16 and DIP-16 packages. It operates over an ambient temperature range of -40 to +85.
