2 x 6 W hi-fi audio power amplifier

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.
