Philips Semiconductors 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.
