ICs for Audio Common Use

AN7511, AN7511S

1-W BTL audio power amplifier

■ Overview

The AN7511 and AN7511S are the audio power am­plifier ICs with 1-ch output. The BTL (Balanced Trans­former-Less) method can provide fewer external parts and
more easy design for applications.

■ Features

• 1-W output (8 Ω) with supply voltage of 5 V: AN7511

• 0.5-W output (16 Ω) with supply voltage of 5 V: AN7511S

• On-chip standby function

• On-chip muting function

■ Applications

• Televisions, radios, and personal computers
