Product specification

2 x 6 W hi-fi audio power amplifier

TDA1521A

GENERAL DESCRIPTION

The TDA1521A is a dual hi-fi audio power amplifier encapsulated in a 9-lead plastic power package. The device is

especially designed for mains fed applications (e.g. stereo tv sound and stereo radio).

Features

• Requires very few external components

• Input muted during power-on and off

(no switch-on or switch-off clicks)

• Low offset voltage between output and ground

• Excellent gain balance between channels

• Hi-fi according to IEC 268 and DIN 45500

• Short-circuit-proof

• Thermally protected.
