General Description

The SGM4703 is a high-power, high efficiency, stereo Class-D audio power amplifier with adjustable power limit (APL) and automatic level control (ALC).

It operates with a wide range of supply voltages from 5V to 26V.

With 24V supply voltage, it can deliver 2 × 40W peak output power for a pair of 8Ω speakers with 10% THD+N.

Key Features

APL and ALC. The APL limits peak audio outputs to a user-defined value to protect audio speakers from excessive power dissipation or over-load. The APL and ALC adjust the voltage gain of the audio amplifiers in response to over-limit audio inputs, eliminating output clipping distortion while maintaining a maximally allowed dynamic range of audio outputs. The limiting voltage of APL and ALC can be either a user-defined value or the supply voltage. The SGM4703 can be configured into driving either.
