SGM4812

132mW Differential Input,

Stereo Audio Power Amplifier

GENERAL DESCRIPTION

FEATURES

The SGM4812 is a stereo audio power amplifier with

differential inputs. Operating on a single 5V power

supply, it delivers 132mW of continuous RMS power

per channel into a 16Ω loads with typically 0.1%

THD+N. Amplifier gain is externally configured by

means of two resistors per input channel and does not

require external compensation.

● Dual Channel, Differential Inputs

● 132mW into 16Ω Load from 5V Power Supply at

THD+N = 0.1% (Typical, per Channel)

● 82mW into 32Ω Load from 5V Power Supply at

THD+N = 0.1% (Typical, per Channel)

● 2.7V to 5.5V Operation

● Thermal Shutdown and Short Circuit Protection

● Internal Pop Reduction Circuitry

The SGM4812 is designed to maximize audio

performance in portable communication device

applications such as mobile phone. The portable

application requires audio power amplifier has

minimum of external components and can operate from

a single 2.7V to 5.5V power supply.

● Internal Mid-Rail Generation

● Low Shutdown Current: 0.36μA (TYP) at 5V

● Shutdown Pin is Compatible with 1.8V Logic

● -40℃ to +85℃ Operating Temperature Range

● Available in Green MSOP-10 Package

The SGM4812 features an externally controlled,

active-high, micro-power consumption shutdown mode.

Additionally, the SGM4812 features an internal thermal

shutdown and short circuit protection mechanism.
