SGM4863 – Dual 2.1W Audio Power Amplifier

SGM4863 is a single-channel digital gain regulator (Digital Variable Gain Amplifier) manufactured by SG Micro Corp. This IC is used to control the volume or sensitivity of the sound by adjusting the gain of the audio signal.

Part Number: SGM4863

Function: 2.1W, Dual bridge-connected audio power amplifier

Package: TSSOP-16, TSSOP-20, TQFN-3×3-20L, SOIC 16, DIP 16 Pin Type

Manufacturer: SG Micro Corp ( )


SGM4863 datasheet


SGM4863 is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, will deliver 2.1W into a 4Ω load or 2.5W into a 3Ω load with typically 1% THD+N. In addition, the headphone input pin allows the amplifiers to operate in single-ended mode when driving stereo headphones.

To simplify audio system design, the SGM4863 combines dual bridge speaker amplifiers and stereo headphone amplifiers on one chip.



1. 2.5W into 3Ω Load from 5V Power Supply at THD+N = 1% (Typical, per Channel)

2. 2.1W into 4Ω Load from 5V Power Supply at THD+N = 1% (Typical, per Channel)

3. 1.3W into 8Ω Load from 5V Power Supply at THD+N = 1% (Typical, per Channel)

4. Low Shutdown Current: 0.03μA

5. Operation Supply Voltage: 2.8V to 5.5V

6. Stereo Headphone Amplifier Mode
