SGM4890 Datasheet (Shengbang Microelectronics)

SGM4890, 1.1W Audio Power Amplifier

The SGM4890 is a fully-integrated audio power amplifier which operates from 2.5V to 5.5V supply voltage.

It can deliver 1.1W into an 8Ω BTL load from 5V supply at THD+N = 1%.

It is designed for portable application that needs low-component count.

The SGM4890 has a low power consumption shutdown mode
