BTL Audio Power IC AN7510/7520 Series
■ Overview
The AN7510/7520 series is a 0.5W to 3W BTL audio power amplifier IC. Equipped with a standby function and mute or DC
volume circuit, the series includes a lineup of single and dual output models. With simplified set design due to minimum
external components, this IC has a wide variety of applications.
■ Features
• Operating power sourcs voltage: 3.0V to 13.5V.
• Built-in standby function.
• Built-in mute or DC volume circuit.
