SGM4888

Dual 2.1W Audio Power Amplifier

Plus Stereo Headphone &3D Enhancement

GENERAL DESCRIPTION

FEATURES

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%.

 Supply Voltage Range: 2.8V to 5.5V

 2.5W into 3Ω Load from 5V Power Supply at

THD+N = 1% (Typical, per Channel)

 2.1W into 4Ω Load from 5V Power Supply at

THD+N = 1% (Typical, per Channel)

 1.3W into 8Ω Load from 5V Power Supply at

THD+N = 1% (Typical, per Channel)

 Shutdown Current: 0.02μA (TYP)

 PSRR: 80dB (TYP)at 217Hz

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.
