GENERAL DEscriptION

The SGM4996 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 SGM4996 has pop/click suppression circuitry, low power consumption shutdown mode and thermal shutdown protection. The shutdown function may be realized by either a logic high or low, which is up to the voltage acted on the SD MODE pin.

Bootstrap capacitors or output coupling capacitors are not needed.

The SGM4996 is available in Green MSOP-10, TDFN-3×3-10L and MSOP-8 packages. It operates over an ambient temperature range of -40℃ to +85℃.
