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.
