SGM4700 High-Power Stereo Class-D Audio Power Amplifier

The SGM4700 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 20V. With 15V supply voltage, it can deliver 2 × 23W output power for a pair of 4Ω speak.

SGM4700 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 maintai
