SGM4871

2.4W Stereo Audio Power Amplifier

with Shutdown Mode

GENERAL DESCRIPTION

FEATURES

The SGM4871 is a mono bridge-connected audio

power amplifier which operates from 2.5V to 5.5V

supply voltage. It can deliver 2.4W into a 4Ω load from

5V supply at THD+N = 10%. It is designed for portable

applications. The external gain-setting resistors can

configure the unity-gain stable of the device.

• Supply Voltage Range: 2.5V to 5.5V

• Output Power at THD+N = 10%, 1kHz

SGM4871YPS8: 2.4W (TYP) into 4Ω Load

SGM4871YS8: 1.5W (TYP) into 8Ω Load

• Shutdown Current: 0.07μA (TYP)

• No Output Coupling Capacitors

• External Gain Configuration Capability

• Unity Gain Stable

The SGM4871 has low power consumption shutdown

mode and thermal shutdown protection.

• Thermal Overload Protection Circuitry

• -40℃ to +85℃ Operating Temperature Range

• Available in Green SOIC-8 (Exposed Pad) and

SOIC-8 Packages

The SGM4871 is applied to low power portable

systems. Output coupling capacitors, bootstrap

capacitors or snubber networks are not needed.

The SGM4871 is available in Green SOIC-8 and

SOIC-8 (Exposed Pad) packages. It operates over an

ambient temperature range of -40℃ to +85℃.

APPLICATIONS
